Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
the name of the element that contains 17 protons is chlorine
The element is calcium. It has an atomic number of 20, which corresponds to the number of protons. The sum of protons and neutrons gives the atomic mass number, which is 40 in this case.
The atomic number of the element refers to the number of protons of an atom: all atoms of an element have this number of protons. A neutral atom of the element will have the same number of electrons.
Boron is an element and contains only atoms of Boron.
Protons are protons, no matter what element they are in.
Boron has 5 protons
The number of protons in an atom is its atomic number.
Boron
it's Uranium
Yes, all atoms with the same number of protons will have the same name. The number of protons in an atomic nucleus is what we use to number the elements. Elements with the same number of protons are the same element, as the identity of an element is due solely to the number of protons in its nucleus.
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.

Lead (Pb)
Neutral atoms of the same element can differ in their number of neutrons. This difference in the number of neutrons gives rise to isotopes of that element.
Yttrium is the name of the chemical element that has exactly 39 protons in the nucleus of each of its atoms.
Boron. Symbol: B. its a nonmetal too.
