Element
An element is a substance whose atoms all contain the same number of protons and the same number of electrons. The number of protons in an element's atom determines its atomic number and defines its chemical identity.
by the atomic number.
Number of protons in the nucleus is 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.
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
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)
An element is a substance in which all atoms have the same number of protons. Each element is identified by its unique number of protons, known as the atomic number.
it protons is the answer.
Element
No two elements have the same number of protons.
A pure substance is a material made of only one type of particle, such as atoms or molecules, and all the atoms in a pure substance have the same atomic number or number of protons. This means that all the atoms in a pure substance are of the same element.
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 an atom is the atoms number of protons. The number of protons is same as the number of electrons.
An element is a substance whose atoms all contain the same number of protons and the same number of electrons. The number of protons in an element's atom determines its atomic number and defines its chemical identity.
