To add or take away energy levels

What happens when magnesium loses 2 electrons?

It stabilizes to a net charge of 0

15. What is a valence electron?

an electron that is found in the outermost shell of an atom.

an electron found in the innermost shell of an atom.

an electron found in the middle shell.

19. If an atom transfers an electron to another atom, those atoms form which bond?

Ionic Bond , which is stronger than a covalent bonds

Covalent Bond , which is stronger than ionic bonds

20. If I was trying to determine if two atoms will bond, what would be helpful to know:

All of the above, all of which can be found on the Periodic Table

Valence electrons, found by group number

Whether the elements are metals or nonmetals

The electronegativity of the atoms

What is the goal of the Lewis Dot Structure?

To show the element's valence electrons & bonding capabilities.

To determine the electron position.

To find the atomic mass of an element.

To search for the number of electrons in an individual atom.

What's a valence electron?

electrons in the outermost energy level

electrons in the second energy level

What is the Octet Rule?

Atoms tend to gain, lose, or share electrons to achieve a stable electron configuration with eight electrons in their outermost shell.

Atoms always have eight electrons in their outermost shell regardless of their bonding behavior.

The Octet Rule applies only to noble gases and not to other elements.

Atoms can only lose electrons to achieve the Octet Rule, never gain or share.

What is the role of noble gases in relation to the Octet Rule?

Noble gases have a full outer shell of electrons (octet) and are generally unreactive, serving as a model for stability.

Noble gases have incomplete outer shells and readily form bonds with other elements.

Noble gases are highly reactive and often participate in chemical reactions to achieve stability.

Noble gases can easily lose or gain electrons to achieve a stable configuration.
