two elements having the same number of protons, but differeing in the number of neutrons; thus having slightly different molecular weights are called isotopes of that element...ex. Boron-10(has an Atomic Mass of 10.012937u) and Boron- 11(has an atomic mass of 11.009305u) Each isotope of Boron has 5 protons, they differed in the number of neutrons which gave each a slightly different atomic mass. note:if two elements have a different number of protons they are no longer the same element or even isotopes of that element..the amount of protons is like a way to identify which atom is which.
A substance whose atoms have the same number of protons in their nucleus are element of each other.
Isotopes and ions of the same element have equal number of protons.

A plasma created from water would include electrons, protons (hydrogen atom nuclei), and oxygen atom nuclei (protons and neutrons). There is no specific name for this substance.
Sodium is an element because it is composed only of sodium atoms, all of which have 11 protons in their nuclei.
Protons are normally found in the nuclei of atoms.

Every element is composed of atoms, all with the same number of protons. The elements are distinguished by the unique number of protons in each of the nuclei of its atoms.

No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.

15 protons.
Protons are normally found in the nuclei of atoms.
The atomic number of boron is 5, and since the atomic number of an element is the number of protons in the nuclei of its atoms, boron atoms have 5 protons in their nuclei.
