How many neutrons and protons are there in an atom?

Answer 1

The number of protons is equivalent to the atomic number which can be got from the Periodic Table. The number of neutrons is the atomic weight minus the number of protons. Again, this information is available from the periodic table.

Answer 2

It depends on the element. The number of protons are determined by what the atomic number of the element is. The number of neutrons are found by subtracting the atomic number from the atomic mass.

Answer 3

The total number of neutrons in an atom is known as its atomic mass. The sum of all the atomic weights of isotopes of a particular element is known as an element's atomic weight. Atomic weights are decimal numbers for this reason.

Answer 4

It depends on the the element which that atom forms.

Every element has a different number of protons and it is the number of protons that characterizes the element. This number is called the Atomic Number.

Protons are positively charged and in an atomic nucleus they are all squashed together. Like charges tend to repel each other and the protons do not like to be next to each other in the nucleus. It is the job of the neutrons (which have no charge) to sit between the protons and stabilize the atom's nucleus.

Atoms can have a variable number of these neutrons and it is the combined mass of the protons and neutrons that comprise the Atomic Mass of the atom. Atoms of an element with various numbers of neutrons are called isotopes of that element, they all have slightly different Atomic Masses but the same Atomic Number.

Answer 5

The number of protons is equal to the atomic number.

The number of neutrons = Mass number of an isotope - Number of protons

Answer 6

This question is inadequate; an average number of protons and neutrons has no sense.

The number of protons in the known today chemical elements is between 1 and 118.

Answer 7

Atomic Mass
