If an atom has a mass number of 12 and an atomic number of 8, this is how many neutrons it has.
What is 4?
300
This is the type of bond formed when electrons are shared between two atoms.
What is a covalent bond?
300
These are the electrons located on the outermost orbital of an atom. They are used for bonding.
What are valence electrons?
300
This is the family name of the inert or unreactive gases.
