Can the atomic mass of individual atoms of an element vary?
The mass of an atom will always remain constant, but various isotopes of the same element may have differing atomic masses. For example, a given hydrogen atom could have a mass of 1 amu, 2 amu, or 3 amu, but it could not switch between them.
When can atoms of the same element vary in the number of?
Atoms of the same element can vary in the number of neutrons they have, resulting in different isotopes of that element. Isotopes have the same number of protons and electrons, but a different number of neutrons, which affects their atomic mass.
What are the atoms of the isotopes of a particular element vary in the number of?
The atoms of the isotopes of a particular element vary in the number of neutrons in their nuclei. While they have the same number of protons (which defines the element), the differing neutron counts result in different atomic masses. This variation in neutrons leads to different isotopes, which can exhibit different physical and nuclear properties.
Do all atoms have the same protons?
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.
Is the element with largest atomic mass always present in highest percentage by mass in a compound?
No, the element with the largest atomic mass is not always present in the highest percentage by mass in a compound. The percentage by mass of an element in a compound is determined by its atomic mass and the total mass of the compound. The composition of a compound can vary based on the number of atoms of each element present.

Neutral atoms of the same element can differ in their number of what?
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
Is the element with largest atomic mass always present in highest percentage by mass in a compound?
No, the element with the largest atomic mass is not always present in the highest percentage by mass in a compound. The percentage by mass of an element in a compound is determined by its atomic mass and the total mass of the compound. The composition of a compound can vary based on the number of atoms of each element present.
Do all elements in the same group have the same atomic mass?
No. Atoms of the same element can have different masses as the number of neutrons can vary. Atoms of the same element but with different masses are called isotopes.
Do all the atoms have the same proton number?
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.
How many atoms are in a particular element are in a compound?
The number of atoms of a particular element in a compound can vary depending on the chemical formula of the compound. You can determine the number of atoms by looking at the subscripts in the chemical formula. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
Distinguishes one element from another element?
Elements are defined by the number of protons contained in the nucleus of their atoms. The number of electrons (the same as protons in neutral atoms) determine an elements chemical interactios with other elements. The number of neutrons (which can vary) determines an element's mass and relative stability.
Is it possible for atoms of the same element to have different chemical properties?
Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
Why does not an atom of an element represent the actual mass of its atom?
An atom of an element does not represent the actual mass of its atom because the atomic mass listed on the periodic table is an average mass calculated based on the relative abundance of different isotopes of the element. Isotopes are atoms of the same element with differing numbers of neutrons, so the actual mass of an atom of a specific isotope may vary slightly from the average atomic mass.
