Yes, it is true, the number of protons is equal to atmic number.
The identity of an element is determined by the number of protons.
The identity of an element is determined by the number of protons in the nuclei of its atoms. This is the atomic number of an element.
the number of its protons
The number of protons in the nucleus determines the identity of the element.
Yes.
Yes, it is the atomic number i.e. number of protons that determines an element's identity.
Protons are positively charged species found inside the nucleus. The number of protons decides what element it is and its position in the periodic table.
The identity of the element is determined solely by the atomic number, which is the number of protons.
The number of protons in an atom's nucleus determines its chemical identity.
The number of protons in the nucleus determines what element it is. There can be different isotopes that have more or less neutrons, and there can be ions meaning they're positively or negatively charged which means they've lost an electron or gained an extra one.
An element can be identified by the number of protons in the nucleus of its atoms.
The atomic number of an element is determined by the number of protons in its nucleus.
