Question 28

covalent bond

Answer 28

a chemical bond between to atoms sharing the same electron

Question 29

valence electrons

Answer 29

electrons that belong to the outermost energy level of an atom; they are the electrons involved in chemical bonding

Question 30

How to

draw an atom

Answer 30

first make the nucleus containing protons and neutrons, draw circles around it to for the number of energy levels, with dots on these for electrons, empty electron spots should be blank circles.

The amount of protons and electrons is equal to the atomic number, while you find the number of neutrons by subtracting the rounded mass number by the atomic number, or protons.
