istope
The nucleus of an atom contains protons and neutrons. Different amount of neutrons- Isotopes. Different amount of protons- Different element.
An isotope is an atom that contains a different number of neutrons. In order for an element to change there has to be a different number of protons.
This is the isotope radium-226.
Each element has a different number of protons and neutrons. So it changes for each element.
Isotopes have the same amount of protons but a different amount of neutrons.
The nucleus of an atom contains protons and neutrons. Different amount of neutrons- Isotopes. Different amount of protons- Different element.
Boron is an atom or element, and it contains protons, electrons, and neutrons.
Be or beryllium
An isotope is an atom that contains a different number of neutrons. In order for an element to change there has to be a different number of protons.
This is the isotope radium-226.
Each element has a different number of protons and neutrons. So it changes for each element.
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
Isotopes have the same amount of protons but a different amount of neutrons.
It is an isotope of the element.
Each chemical element has a different number of protons; the number of neutrons can be similar.
The isotopes of an element are alike in that they have the same number of protons, electrons, and the same chemical properties. The isotopes are different in that they have different numbers of neutrons and thus different atomic masses.
They have the same number of protons and different number of neutrons.
