When they are of the same element.
No, different samples of an element can have varying atomic masses due to the presence of isotopes. Isotopes are atoms of the same element with different numbers of neutrons, leading to different atomic masses.
If two atoms have the same atomic number, it means they have the same number of protons in their nucleus. If they also have the same atomic mass, it means they have an equal number of protons and neutrons. These atoms would be isotopes of the same element.
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.
No, atomic mass and atomic diameter are not the same thing. Atomic mass refers to the mass of an atom, which is the sum of the protons and neutrons in the nucleus, while atomic diameter refers to the size of the atom, often measured as the distance between the nuclei of two bonded atoms.
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.
When two atoms appear to have the same mass number, it means they have the same total number of protons and neutrons. However, they may have different atomic numbers, meaning they are different elements. This can occur with isotopes, where atoms of the same element have the same mass number but different numbers of neutrons.
isotope
Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.
There is an average atomic mass because all atoms of the same element do not have the same amount of neutrons (isotopes), therefore variations in atomic mass exist. The average atomic mass of an element is the estimated average of all the atoms of the same element, given the average of different isotopes in a scientific sample.
They would have to be atoms of the same element, and the same isotope of that element.
Atoms atomic number represents their number of protons.
No, different samples of an element can have varying atomic masses due to the presence of isotopes. Isotopes are atoms of the same element with different numbers of neutrons, leading to different atomic masses.
If two atoms have the same atomic number, it means they have the same number of protons in their nucleus. If they also have the same atomic mass, it means they have an equal number of protons and neutrons. These atoms would be isotopes of the same element.
They don't. Sulphur has about twice the atomic mass of oxygen.
Yes, that is correct. Isotopes are atoms of the same element with the same number of protons (atomic number) but different numbers of neutrons (atomic mass). This difference in neutrons results in isotopes having different atomic masses.
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.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
