Element
An element is a substance made up of atoms which all have the same number of protons (which is the atomic number of the atom).
by the atomic number.
Atomic number is the number of protons in an atom, not the number of atoms. The element with the atomic number 15 is phosphorus.
Iron has an atomic number of 26, which means its atoms have 26 protons in their atomic nuclei. Cobalt has an atomic number of 27, which means its atoms have 27 protons in their atomic nuclei. The number of protons defines an element.
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
The atomic number of an element is the number of protons in its nucleus. The number of protons define what the element is.
A pure substance in which all the atoms have the same atomic number or number of protons is an element.
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
it protons is the answer.
Element
No two elements have the same number of protons.
The number of protons in the atomic nucleus is equal to atomic number.
Protons.
All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
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.
The atomic number of an atom is the atoms number of protons. The number of protons is same as the number of electrons.
The atomic number is equal to the number of protons.
no. -------------- In atoms, only the Protons count as atomic number The neutrons and the protons together is as the atomic mass
