Question

.
What is the total number of protons, neutrons, and electrons in a cadmium, Cd, atom that has a mass number of 112?

Answer 1

Answer:

160

Explanation:

Protons and electrons are the same (aka the ATOMIC NUMBER OR NUMBER AT THE VERY TOP OF THE ELEMENT) So 96 next find the neutrons that would be the atomic mass ( aka the NUMBER AT THE VERY BOTTOM OF THE ELEMENT) - The atomic number so 64.412

next we add the protons/electrons + the amount of neutrons we got and that would be the total!

so 160.412 but if we rounded down it would be 160

hope it helped!!!

Answer 2

The total number of protons, neutrons, and electrons in cadmium, Cd are:

The number of protons = 48

The number of neutrons = 64

The number of electrons = 48

What are protons, electrons, and neutrons?

Protons, electrons, and neutrons are subatomic particles. They are present inside an atom. An electron contains a negative charge. A proton contains a positive charge and a neutron has no charge.

The mass of any atom is the sum of its proton and neutron

So, mass =  proton + neutron = 112.

The atomic number of cadmium is 48 which is also the number of electrons of the element.

The number of protons is equal to the number of electrons, so the number of protons will be 48.

Now, the number of neutrons of Cd is?

proton number + neutron number = 112

proton number = 48, hence

48 + neutron number = 112

neutron number = 112 - 48 = 64

Therefore, the number of neutrons is 64.

Thus, the number of protons = 48

The number of neutrons = 64

The number of electrons = 48
