Isotopes have the same number of protons but a different number of neutrons. Different isotopes of a single element are on the same position on the Periodic Table of elements. The existence of isotopes was first suggested in 1913 by a radiochemist named Frederick Soddy.

What are the different numbers of neutrons called when two atoms have the same number of protons?

Two atoms with the same number of protons but different numbers of neutrons are called "isotopes".


What is the name given to atoms of the same element that have the same number of protons?

Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.


An atom that has more neutrons than protons is called what?

An atom that has more neutrons than protons is called an Isotope.


What atoms containing the same numbers of protons and different numbers of neutrons are?

These atoms are called isotopes.


What are atoms containing the same numbers of protons and different numbers of neutrons are?

Atoms containing the same number of protons but different numbers of neutrons are called isotopes. Isotopes have the same atomic number (number of protons) but differ in atomic mass due to the varying number of neutrons.


How do the numbers of protons neutrons and electrons for an element compare?

In the neutral state, all atoms of the same element contain equal numbers of protons and electrons. However, most elements have atoms with different numbers of neutrons. These are called isotopes.


Atoms that have different number of protons and neutrons are called?

Atoms which have different number of protons and neutrons but have the same molecular weight are called Isobars.


What are atoms that have the same number but different weights?

Atoms that have the same number of protons but different weights are called isotopes. Isotopes of an element have the same atomic number (number of protons), but a different atomic mass (sum of protons and neutrons) due to varying numbers of neutrons.


What are two elments with the same number of protons but a different number of neutrons called?

Two atoms with the same number of protons are not two elements but one element. If they have differing numbers of neutrons, however, they are said to be of different isotopes.


What are the different forms called in an element that has forms with different numbers of neautrons?

Atoms of the same element can have different numbers of neutrons; the different possible versions of each element are called isotopes. For example, the most common isotope of hydrogen has no neutrons at all; there's also a hydrogen isotope called deuterium, with one neutron, and another, tritium, with two neutrons.


Atoms of an element can have different numbers of protons?

No, they can't. Atoms (be careful of the difference between atoms and ions) can only have different numbers of neutrons, and those are called isotopes.


What are the diffrent forms called in an element that has forms with diffrent numbers of nuetrons?

Isotopes are different forms of an element that have the same number of protons but different numbers of neutrons.
