What is a pure substance - all the atoms have the same atomic number or number of protons?
A pure substance in which all the atoms have the same atomic number or number of protons is an element.
What is a substance in which one or more atoms have the same number of protons or atomic number?
Element
What determines the atomic number of a substance?
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)
A is substance in which one or more atoms have the same number of protons?
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.
A unique substance composed of atoms having the same atomic number?
it protons is the answer.
A substance in which one or more atoms have the same number of atomic number?
No two elements have the same number of protons.
What is a pure substance all the atoms have the same atomic number or 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.
What is number of protons of an atom is the atoms atomic number?
The number of protons in the atomic nucleus is equal to atomic number.
Atomic number is the number of an atoms what?
Protons.
What are Atoms with the same number of protons are?
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.
What are the atomic number?
The atomic number of an atom is the atoms number of protons. The number of protons is same as the number of electrons.
A substance whose atoms all contain the same number of protons and the same number of electrons are?
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.
