VOCAB
Definition for isotopes
Atoms of an element with the same number of protons but different numbers of neutrons.
Symbols for elements in table salt
What is Na & Cl?
The importance of valence e-
These electrons are important BECAUSE:
1- they determine the electronegativity
2- they show the electron affinity
3- and ionization energy
which GOVERNS covalent & ionic bonds
Elements found in Hydrogen Peroxide.
What is Hydrogen & Oxygen?
WHY to use Lewis Dot Structures?
The diagram represents the valence e- of atoms and, therefore the availability to form chemical bonds.
