2. The number of protons and neutrons in a nucleus is the

a. Atomic mass

c. Mass number

b. Atomic number

d. Nucleons

▪The number of protons plus neutrons is the atomic mass.

3. Carbon has 6 protons. How many electrons does Carbon have?

a. 2

b. 4

c. 6

d. 8

▪It has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons.

4. Sodium has an atomic number of 11. How many protons does Sodium

(Na) have?

a. 5

b. 10

c. 11

d. 12

▪Number of Protons (Na) = 11

5. Hydrogen has one (1) proton and electron. How many neutrons does Hydrogen have?

a. 1

b. 2

c. 3

d. zero

▪Number of Neutrons (Hydrogen) = 0/zero

6. Who discovered that orbital helps us to predict the area where we can find electrons?

a. Bohr

b. Dalton

c. Rutherford

d. Schrodinges

▪Niels Bohr discovered that orbital helps us to predict the area where we can find electrons.

Hope it helps!
