Atoms of different element can not have same atomic number because only same type of atoms combine to form element. Atoms belonging to different element can have different atomic number. Therefore, the element arranged in order of increasing ionization energy are Gallium, Phosphorus, Chlorine, Fluorine.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same. Two or more than two atoms with different physical or chemical properties can not combine together to form an element.
For neutral atoms, ionization energy is positive, indicating that ionization is indeed an endothermic process. The higher the ionization energy of an atom, roughly speaking, the nearer the outer electrons are to nucleus. The element arranged in order of increasing ionization energy are Gallium, Phosphorus, Chlorine, Fluorine.
Therefore, the element arranged in order of increasing ionization energy are Gallium, Phosphorus, Chlorine, Fluorine.

Explanation:
Astronomers observed that the orbit of Uranus was not uniform. Therefore, they hypothesized the existence of another planet. This is an example of scientific investigation being led by _____.
Inductive Reasoning
Deductive Reasoning
Answer:
This is an example of scientific investigation being led by inductive reasoning.
Explanation:
Inductive reasoning is the type of reasoning used to make broad generalizations from specific observations. We have certain pieces of data and make conclusions based on them. In the given example, astronomers have made a specific observation - that the orbit of Uranus isn't uniform. Based on that fact, they made a broader conclusion - that there is another planet. There are probably more things that could lead to the same conclusion.
The opposite is deductive reasoning, where a person starts off with a broad generalization and tries to make specific, logical conclusions based on it.
Brian is making a cake for his friend's birthday. He combines the ingredients for the cake and then pours the batter into two pans and bakes them for 45 minutes in the oven. While the pans are in the oven, he combines butter, sugar, and milk and mixes them together to make the icing. What type of changes created the cake and the icing?
A. Both the icing and the cake are formed by physical changes.
B. Both the icing and the cake are formed by chemical changes.
C. The icing is formed by a chemical change and the cake is formed by a physical change.
D. The cake is formed by a chemical change and the icing is formed by a physical change.
Answer:
it’s D.The cake is formed by a chemical change and the icing is formed by a physical change
Explanation:
It’s because when the cake was baking there was nothing physical about it so it was a chemical change the icing is formed by a physical change because all you did was mix three ingredients together
The type of changes that created the cake and the icing is;
Option D; The cake is formed by a chemical change and the icing is formed by a physical change.
This is about understanding type of changes in chemistry.
Physical change is defined as a change that affects the form of a compound or element but it doesn't affect its' chemical composition.Meanwhile, chemical change is defined as a change that affects the composition of a compound and a new substance is formed.Now, for brian's cake he has combined raw ingredients into two pans and bakes the cake. For the cake to be baked, it means the ingredients mixed have changed from liquid to solid and also a new substance has been formed. Thus, we can say that the cake was formed from chemical change.Meanwhile, the icing was formed by physical change because it did not undergo any chemical process and no new substance was formed as only butter, sugar and milk were mixed together.Read more at; https://brainly.com/question/19046658

Explanation:
Scientists digging in a cave found an unknown substance. The scientists
found that the substance’s molecules were moving around each other. The scientists
increased the speed of the substance’s molecules and caused a phase change. How
did the scientists do this, and how did this affect the substance?
Answer:
By adding heat energy
It became a gas
Explanation:
The molecules moving about another is a clear indicator that the substance is a liquid.
In a liquid, the molecules stick together and move about one another.
When the scientist increase the speed of the of substance, the kinetic energy increases. if this increase causes a phase change, then the substance becomes a gas. So, by adding heat energy a substance becomes gaseous if it is a liquid already.check wether all the answers are correct or not. please?

When writing a formula for a compound having a transition metal in it, _____.
it is sometimes necessary to use the Roman numeral as the assigned charge of the metal
it is sometimes necessary to include a Roman numeral after the symbol of the metal
it is always necessary to include a Roman numeral after the symbol of the metal
it is always necessary to use the Roman numeral as the assigned charge of the metal
Answer:
The correct option is;
It is always necessary to include a Roman numeral after the symbol of the metal
Explanation:
The transition metals can form ionic compounds with other elements by giving different number of electrons such that the transition metals can combine to form compounds in which they have different oxidation states
Therefore, in a compound formed by a transition metal, the value of the transition metal's valency or oxidation state in the compound is indicated by the inclusion of an equivalent Roman numeral after the transition metal in the name of the chemical formula of the compound

Answer:
A unit of substance that contains the Avogadro number of atoms or molecules is referred to as a mole of the substance.
Explanation:
The mole (symbol: mol) is the unit of measurement for amount of substance in the International System of Units (SI). A mole of a substance or a mole of particles is defined as exactly 6.02214076×1023 particles, which may be atoms, molecules, ions, or electrons. In short, for particles, 1 mol = 6.02214076×1023.

gasoline is separated from crude oil by heating it until it reaches it's boiling point. which separation method is used?
Answer:
Fractional distillation
Explanation:
The separation of gasoline from crude oil by heating until it reaches its boiling point is a separation technique called fractional distillation.
It is the separation of a mixture, such as crude oil into their respective fractions. This is achieved due to the differences in boiling point between the constituent fractions in the mixture. As the boiling point of a fraction is reached, it distills out from the column.is orange juice a element or a mixture
Orange juice is mixture.
Answer:
[tex]\boxed {\boxed {\sf Mixture}}[/tex]
Explanation:
An element is pure and all the atoms have the same atomic number. An element has a symbol and can be found on Periodic Table of Elements.
A mixture is created when two or more substances are combined physically.
Orange juice can't be found on the Periodic Table of Elements. Orange juice is made up of many different substances/ingredients, like water, sugar, and juice from the orange.
Therefore, orange juice is considered to be a mixture. More specifically, a homogenous mixture because it is uniform. (*applies to pulp-free orange juice). If it has pulp, it would be a heterogenous mixture.
carbon and tin are both in the fourth column of the table which would you expect to have the greater electronegativity
Answer: Carbon
Explanation:
electronegativity decreases when you go down a column
The study of chemical bonds is called chemistry.
The correct answer is carbon.
The more negative charge present on an atom shows the electronegativity.
The attraction of the nucleus to the proton is also referred to as electronegativity.
The smaller the radius more the electronegativity.
Hence, the correct answer is Carbon as it has fewer atoms and a smaller radius.
