All of them.
All atoms of a given element have the same number of protons in a nucleus. It is the number of protons in an atom's nucleus that determines the elemental identity of any atom. Period.
The number of protons in the nucleus of its atoms.
No because the number of protons never changes or else the element changes.
#of electrons and # of protons is EQUAL in a neutral atom
Lead has more protons in the nucleus of its atoms compared to tin. Lead has 82 protons while tin has 50 protons in its nucleus.
The nuclei of all atoms of a given element always have the same number of protons. This number is unique to each element and is known as the element's atomic number.
protons and electrons will always be = number
Number of protons
yes
All atoms of a given element have the same number of protons in a nucleus. It is the number of protons in an atom's nucleus that determines the elemental identity of any atom. Period.
Uncombined atoms have the same number of neutrons as protons only if they are isotopes of the element, which means the atoms have the same number of protons but different numbers of neutrons. Otherwise, atoms with the same number of protons and neutrons would be considered as different elements.
protons and electrons
when the protons changes, then the two atoms belong to two different elements.
The number of protons in the nucleus of its atoms.
Protons are found in the nucleus of atoms along with the neutrons of the atom. The nucleus is always in the centre of the atom.
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.
No. Each type of atom (element) has its own unique number of protons, which is called the atomic number. Atoms of the same element will always have the same atomic number (number of protons). Atoms of different elements will never have the same atomic number (number of protons).
