The number of protons in the nucleus will ALWAYS be the same for a specific element.
(ex: Hydrogen always has EXACTLY 1 proton)
But, the number of electons and neutrons can vary in a particular element.

∙ 10y agoAtoms are composed of the subatomic particles electrons, protons, and neutrons. Elements are composed of one kind of atom. The identity of an element is determined by the number of protons in the nuclei of its atoms, which is called its atomic number. All atoms of the same element have the same number of protons.

What subatomic particles controls the identity?
This particle is the proton which is equal to the atomic number.
How does atomic mass indicated element reactivity?
There is no good correlation lies between the element reactivity and the atomic mass.
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
Describe the Reactivity of group 1 element varies with increasing atomic number?
describe how the reactivity of group1 elements and group 7 elements varies with increasing atomic number
The neutral particle of an atom weighing approximately one atomic mass unit?
This atomic particle is the neutron.
What subatomic particles controls the identity?
This particle is the proton which is equal to the atomic number.
Tiny particle in an atom that has a negative charge?
The main negatively charged particle in an atom is the electron. The electron controls the reactivity of an element. An even smaller particle is a quark, which composes protons and neutrons. Quarks can be either positively or negatively charged.
How does atomic mass indicated element reactivity?
There is no good correlation lies between the element reactivity and the atomic mass.
What is the reactivity for the halogens?
The reactivity of halogens decreases with increasing atomic number.
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
Which atomic particle has an atomic mass of one amu but no net charge?
This atomic particle is the neutron.
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
How does the reactivity of an atom with an atomic number of 10 compare to the reactivity of an atom with an atomic number of 5?
Boron (atomic number 5) is more reactive than neon (atomic number 10).
An atomic particle that is positively charged?
This particle is the proton.
What is the negative subatomic particle in an atom is called?
Negatively charged sub-atomic particle: electron. Positively charged sub-atomic particle: proton. Neutrally charged sub-atomic particle: neutron.
Describe the Reactivity of group 1 element varies with increasing atomic number?
describe how the reactivity of group1 elements and group 7 elements varies with increasing atomic number
A neutral atomic particle called a proton?
A neutral atomic particle is called a proton. This is taught in science.
