Covalent Bond Video

Covalent Bond Video. A covalent bond is the chemical bond formed between two ?atoms when they share electrons in pairs. When atoms come ?near each other, their electrons are attracted towards the ?nucleus of the other atom. If the outside shell is not filled, this ?attraction becomes stonger.

Types of Bonds

Types of Bonds. Unit 4 Topic 2. Ionic Bonding. An Ionic bond forms when two atoms exchange electrons. Ions. The atom which loses electrons , forms a positive ion , (cation) and is a metal The atom which gains electrons , forms a negative ion (anion) and is a nonmetal.

Basics of matter

Basics of matter. Atoms -The building blocks of matter Atoms are composed of 3 types of particles: protons (positively charged) neutrons (no electric charge) electrons (negatively charged) Atoms become different elements depending on the number and ratio of these three particles. The atom.
