What is a covalent bond?
A bond in which valence electrons are shared between 2 nonmetal atoms
Proton charge?
Positive
Which groups are the most reactive?
Halogens and alkali metals
What do elements in the same period share in common?
Number of valence shells
What is an ionic bond?
Transfer of electrons between a metal and a nonmetal
Neutron charge?
neutral charge
Which group of elements are the most inert? What does this mean?

What is the balanced ionic formula between Magnesium and Phosphorus? Use periodic table for this, figure out how many Mg and P.
Mg3P2
Atomic Number
number of protons in one atom of an element
If an atom is less electronegative, what does that mean in a covalent bond?
This is the atom that will be bullied in the covalent relationship and will not have as much of a turn with the shared electrons
