The atomic number refers to the number of protons (positively charged subatomic particles) in the nucleus of the atom, whereas the Atomic Mass is the mass of atoms relative to one 12th the mass of an atom of carbon 12. Sometimes an element will be listed as having more than one atomic mass even though the atomic number stays the same, this is due to isotopes. This is when an atom has the same number of protons, but a different number of neutrons (another subatomic particle) in the nucleus. For example, Carbon 12 and Carbon 14 both have the atomic number 6 because they both have 6 protons in the nucleus. However, carbon 12 has 6 neutrons whereas carbon 14 has 8. This accounts for the difference in mass.

∙ 11y agothey are called isotopes. the # of neutrons do change, but not the # of protons and electrons. isotopes are the diff. versions of an atom. for example B-11 and B-12. isotopes have diff. # of mass that average out as the avg. atomic mass.

What are Atoms that vary in the number of neutrons found in their nuclei called?
Different elements with same number of neutrons are known as isotones.
Is mixtures or isotopes are atoms of the same element with different numbers of neutrons?
Atoms have isotopes: it is true, the isotopes of the same element have different number of neutrons.
Isotopes exist because atoms of the same element can have a different numbers of what?
Isotopes are different atoms of the same element with the same number of protons (proton number) but different in number of neutrons. Given that nucleon number is equal to the sum of proton and neutrons in the nucleus of an atom, isotopes have different nucleon number due to difference in number of neutrons.
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.
What are the requirements for two atoms to be isotopes of each other?
The same elements may be isotopes , because it contains a different number of neutrons in the nucleus. Hydrogen exhibits three different isotopes. viz:- #1 ; protium ; 1 proton, 0 neutrons, 1 electron #2 ; deuterium ; 1 proton, 1 neutron, 1 electron #3 tritium ; 1 proton, 2 neutrons, 1 electron NB Notice the different number of neutrons.
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 vary in the number of neutrons found in their nuclei called?
Different elements with same number of neutrons are known as isotones.
Do different atoms of the same element have you identical number of neutrons?
The number of neutrons is different for each isotope.
Do atoms have different number of neutrons?
yes
Are atoms of the same element that have the same number of protons but have different number of neutrons?
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
What is different about the atom of an isotope?
The atoms of an isotope of one particular element are different from other isotopes of the same element because their atoms have a different number of neutrons.
What will always be different in the isotopes atoms?
The number of Neutrons in an isotope will always be different.
What atomic particle that determines a specific isotope?
The atomic particle that determines a specific isotope is the number of neutrons in the nucleus of an atom. Isotopes are different forms of an element that have the same number of protons but a different number of neutrons. The number of neutrons affects the mass of the atom and gives rise to different isotopes with varying atomic weights.
What isotopes are atoms of the same elements with different number of?
Isotopes are atoms of the same elements with different number of neutrons.
Do all atoms of the same element contain the same number of netrons?
No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.
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".
Which atoms that are same element and have the same number of protons but have different number of neutrons?
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
