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.
Atoms with different numbers of neutrons of the same element are called isotopes. Isotopes have the same number of protons but different numbers of neutrons, which can result in different atomic weights. Isotopes of an element behave chemically the same, but may have different physical properties such as stability and radioactive decay.
they 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.
Atoms with the same number of protons but different numbers of neutrons are said to be isotopes of the original atom.

What are Atoms that vary in the number of neutrons found in their nuclei called?
Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.
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?
Basically,there are two things that make 2 atoms isotopes 1: there atomic number should be same(Number of protons/electrons should be the same) 2:there mass number (i.e number of neutrons+protons) should be the same. Hope this helps
What atom of an element with a different number of neutrons?
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.
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 will always be different in the isotopes atoms?
The number of Neutrons in an isotope will always be different.
What are Atoms that vary in the number of neutrons found in their nuclei called?
Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.
Do all atoms of the same element contain the same number of netrons?
No, atoms of the same element can have different numbers of neutrons. These variations in neutron number result in different isotopes of the element.
What atomic particle that determines a specific isotope?
Atoms are electrically neutral. The number electrons and number of protons in neutral atoms are same. The number of neutrons in some atoms are same as the number of protons. Example: Calcium atom contains 20 protons and 20 neutrons. But some atoms contain same number of protons but different number of neutrons. For example carbon atoms exist in three forms - all contain 6 protons but some contain 6 neutrons, some 7 neutrons and others with 8 neutrons. These type of atoms are known as isotopes Definition of isotope: Atoms with same number of protons but different number of neutrons It shows that the different number of neutrons determines the existence of isotopes.

What isotopes are atoms of the same elements with different number of?
Isotopes are atoms of the same elements with different number of neutrons.
Isotopes are atoms of the same element that have a different number of .?
Masses.
What are atoms that have the same element but different neutrons?
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.
Do uncombined atoms have the same number of neutrons as protons?
Uncombined atoms have the same number of neutrons as protons only if they are isotopes of the element, which means the atoms have the same number of protons but different numbers of neutrons. Otherwise, atoms with the same number of protons and neutrons would be considered as different elements.
