Question

. What is the total number of protons, neutrons,

and electrons in a cadmium, Cd, atom that has
a mass number of 112?
PLEASE I NEED HELP

Answer 1

# of Proton: 48

# of Electron: 48

# ofNeutron: 64

Step-by-step explanation:

The atomic number of cadmium is 48.

∴ atomic number = protons = electrons = 48.

Neutrons = mass number - atomic number

∴ Neutrons = 112 - 48 = 64.

⇒ number of protons= 48; neutrons= 64; electrons=48
