An atom has 13 protons and 14 neutrons. Calculate its mass number.

A=Z+N=13+14=27

An atom has 8 protons, 8 electrons and 8 neutrons. How many particles are in its nucleus?

16 particles (protons and neutrons)

An atom has 16 protons, 16 neutrons, and 16 electrons. How many particles does the atom contain altogether?

16+16+16=48 subatomic particles

An atom has 12 protons and 13 neutrons. Calculate its mass number

A=Z+N=12+13=25

An atom has 20 protons and 20 neutrons. What is its mass number?

A=Z+N=20+20=40

An atom has 7 neutrons and 7 electrons and is neutral. Calculate its number of protons and mass number.

Number of protons = number of electrons =7. // A=Z+N=7+7=14

An atom has a mass number of 23 and 11 protons. How many neutrons does it have?

N=A-Z=23-11=12 neutrons

An atom has 11 protons. How many electrons does a neutral atom have?

11 electrons

An atom has 19 protons and 20 neutrons. How many electrons are present if the atom is neutral?

Number of electrons = number of protons= 19
