How are covalent bonds formed?

• Sharing of electrons
• Transfer of electrons

How are ionic bonds formed?

• Transfer of electrons

Why do elements bond?

• To become unstable

• To create a new element

• To become stable

• To create a new atom

Group numbers on the periodic table help us determine

• The number of valence electrons

• The number of protons

• The number of neutrons

• The atomic number

Valence electrons are found

• in the innermost energy level of an atom

• in the middle energy levels of an atom

• in the outermost energy levels of an atom

• In the nucleus of atoms

What do atoms that form positive ions tend to do?

• lose electrons

• gain electrons

• lose protons

• gain protons
