Atomic number is the number of protons in the nucleus of an atom. Each element has a unique atomic number.
Atomic number: 33 (Atomic mass: 74.92)
The atomic number of helium (He) is 2. This means that helium has 2 protons in its nucleus.
The atomic number of aluminum is 13, which means that it has 13 protons in its nucleus.
The atomic number of barium is 56. This means that a barium atom has 56 protons in its nucleus.
If two atoms have the same atomic number, it means they have the same number of protons in their nucleus. If they also have the same atomic mass, it means they have an equal number of protons and neutrons. These atoms would be isotopes of the same element.
Atomic number: 33 (Atomic mass: 74.92)
Argon's atomic number is 18, which means it has 18 protons in its nucleus.
The atomic number of helium (He) is 2. This means that helium has 2 protons in its nucleus.
The atomic number of aluminum is 13, which means that it has 13 protons in its nucleus.
The atomic number of copper is 29, which means that a copper atom has 29 protons in its nucleus.
We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
The phrase "atomic number" means the number of protons in an atom's nucleus and this is plagiarised.
The atomic number indicates the number of protons or number of electrons in the case of a neutral atom.
The atomic number for neon is 10. This means that neon has 10 protons in its nucleus.
We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
The atomic number of hydrogen is 1, which means that a hydrogen atom has one proton in its nucleus.
We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
