No that is not true. The number of PROTONS determines what the element is.
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.
IsotopesThe number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.
proton you can change the number of neutrons and electrons and still have the same element
The number of protons tells you which chemical element the atom is. The number of neutrons determines the isotope of the element.
An atom's atomic number tells which element it is. The atomic number of an element is equal to its number of protons. The number of neutrons may vary within an element, giving rise to the concept of isotopes.
Its atomic number. In other words the number of positive protons in the nucleus of each atom and the number of negative electrons surrounding the nucleus of each atom.
The number of protons, which is the atomic number of an element, determines the identity of an element.
The number of protons determines the element. So when neutrons are added, there is no change in the number of protons and helium atom is unchanged.
mostly protons, the neutrons will affect it but it would still be the same element, just a different isotope.
An element is the type of substance it is, for example, oxygen, hydrogen, etc. An atom is the combined particle consisting of electrons spinning around a nucleus, which is made up of protons and neutrons. The number of protons in an atom, not element, determines the type of element it is. If the atom looses a proton, then the element changes to a different one.
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The atomic mass is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
