Which of the following is true?
All atoms have full outer shells with 2 valence electrons.
All atoms have full outer shells with 8 valence electrons.
Atoms have full outer shells with 8 valence electrons, except Hydrogen and Helium
When an atom loses its valence electrons, its outer energy level empties. It then disappears, and the full inner shell becomes the outer shell.
ionic bond
covalent bond
Valence electrons are shared between atoms so their energy levels are full.
Covalent bond
ionic bond
Why do elements form compounds?
To fill their outer shells
To share their outer shells
To empty their outer shells
