All atoms have at least one proton in their core, and the number of protons
determines which kind of element an atom is. For example, an oxygen atom has
Different versions of the same element are called isotopes. Below are isotopes of
oxygen, they all have the same number of protons but different numbers of ...
The atoms of different elements have different numbers of protons. For example,
all oxygen atoms have 8 protons and all sodium atoms have 11 protons.
Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic
number of an element never changes, meaning that the number of protons in the
It is the number of protons that determines the atomic number, e.g., H = 1. ... The
elements hydrogen, carbon, nitrogen and oxygen are the elements that make up
How is a hydrogen atom different from an oxygen atom? To answer these ...
Atomic number of an atom is the number of protons present in it. A periodic table
