Question

how many protons does the elements contain ​

Answer 1

Answer:

For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28. The most common isotope of uranium has 92 protons and 146 neutrons. Its atomic number is 92 and its atomic mass is 238 (92 + 146).

Element Hydrogen

Symbol H

Atomic No. 1

Number of Electrons in Each Shell First 1

Answer 2

A proton is a subatomic particle, symbol p or p⁺, with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particles present in atomic) they vary from one element to another.

eg For hydrogen, the number of protons is 1. For zinc, the number of protons is 30. The element of an atom with 2 protons is always helium. If you are given the atomic weight of an atom, you need to subtract the number of neutrons to get the number of protons.
