How many valence electrons does Hydrogen have?
1 valence electron.
100
Attractive force between oppositely charged ions, which form when electrons are transferred from one atom to another.
What is an ionic bond?
100
Forms when atoms share one or more pairs of electrons.
What is a covalent bond?
100
The smallest source of matter, makes up the entire universe.
What is an atom?
100
The combining of atoms to form molecules or ionic compounds.
What is chemical bonding?
200
How many valence electrons does Beryllium have?

Unlike ionic bonds, the strength of it is weak.
What is the strength of a covalent bond?
200
Chlorine and Sodium bonded together.
What is table salt? (Sodium Chloride)
200
An electron that is found in the outermost shell of an atom and that determines the atom's chemical properties.

400
This class of elements are usually negative ions.
What are nonmetals?
400
A group of atoms that are held together by chemical bonds.
What is a molecule?
400
A bond formed by the attraction between positively charged metals and the electrons around them.
What is a metallic bond?
400
The force of attraction that holds atoms together.
