Question

an element is having 5protons and 6neutrons then find its atomic number​

Answer 1

Explanation:

This means that an atom of hydrogen has one proton, and, if it's neutral, one electron as well. Gold, on the other hand, has an atomic number of 79, which means that an atom of gold has 79 protons, and, if it's neutral, 79 electrons as well.

Atomic Number.

Name Boron

Protons 5

Neutrons 6

Electrons 5

Atomic Number (Z) 5

Answer 2

Answer:

Mass number = protons + neutrons

Explanation:

The mass number of an element is the sum of the protons and neutrons.

The number of neutrons for a given element is the only number that can change and still have the identity of the element stay the same, (because the atomic number is the number of protons).

In this case the mass number would be 11.
