The element whose outermost energy is full with 2 e-

What is Helium?

This determines how an element will bond

What is the # of valence electrons?

The reason atoms have no charge

What is the number of protons = the # of electrons?

Where valence electrons are located

What is the outermost energy level?

The number of valence electrons in group 1 & 2 respectively

What are one and two?

The number of electrons the 1st energy level can hold

What is two?

The reason atoms bond

What is to fill their outermost energy level?

The energy required to remove electrons from atoms

What is ionization energy?

In elements 1-18, the third energy level can hold this many electrons

What is eight?

The reason group 17 gains electrons

What is high electron affinity?

The properties of malleability and ductility are associated with this bond.

What is a metallic bond?

Atoms gain, lose, or share electrons

What is chemical bonding?

Arranged in crystal lattices

How are ionic bonds?

Two of the same type of atoms joined by a covalent bond

What is diatomic molecule?

The type of bond that allows a staple to bend without breaking

What is metallic bonding?

The bond formed by attraction between two oppositely charged ions.

What is ionic bonding?
