atoms of different elements have different masses?
168142
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. ... Isotopes have different mass numbers, though, because they have different numbers of neutrons.

The identity of an atom depends only on the number of protons, not on the number of neutrons. Many elements have atoms with the same number of protons but different numbers of neutrons. Atoms of an element that have different masses are isotopes (EYE-suh-TOHPS).

Understand that isotopes of an element have different mass numbers but the same number of protons. Using the Periodic Table, find the atomic number of the element. The atomic number equals the number of protons. In a balanced atom, the number of electrons equals the number of protons.

The atomic mass unit (u) is a unit that describes the masses of individual atoms and molecules. The atomic mass is the weighted average of the masses of all isotopes of an element. The molecular mass is the sum of the masses of the atoms in a molecule.
963057
The atomic number is the number of protons in an element, while the mass number is the number of protons plus the number of neutrons.

The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. ... Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass.

No. Lr. The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.

All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom. ... The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number.
451311
Protons and neutrons both weigh about one atomic mass unit or amu. Isotopes of the same element will have the same atomic number but different mass numbers. Atomic number, chemical symbol, and mass numberCarbon has an atomic number of six, and two stable isotopes with mass numbers of twelve and thirteen, respectively.

In general, atoms of the same element are not identical as they can be in different states.

The atomic mass of an element is the total number of protons and neutrons in the nucleus of the atom. The mass number is used to calculate the number of neutrons & electrons in one atom of an element. In order to calculate the number of neutrons you must subtract the atomic number from the atomic mass.

Mass number. The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same.
677092
Since the isotopes of any given element all contain the same number of protons, they have the same atomic number. However, since the isotopes of a given element contain different numbers of neutrons,different isotopes have different mass numbers. ... The Atomic number is the number of protons in an atom.

Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties. Atoms cannot be subdivided, created, or destroyed. Atoms of different elements can combine in simple whole number ratios to form chemical compounds.
