The mass number is the average Atomic Mass of all the isotopes that are found in nature.
The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
The element's average atomic mass.
A balanced chemical equation shows that mass is conserved because the total mass of the reactants before a chemical reaction must equal the total mass of the products after the reaction. This is achieved by ensuring that the number of atoms of each element is the same on both sides of the equation. Therefore, what is consumed on the reactant side is equal to what is produced on the product side, preserving total mass.
The mass number of an isotope of an element is equal to its atomic mass number. However, the atomic weight of an element is a weighted average of the isotopes that occur in the element in nature. Because almost all elements have more than one naturally occurring isotope (if they have any), the atomic weights of most elements are not integers, as mass numbers always are.
Platinum is a rare element too. Atomic number of platinum is 78.
The sum of the number of protons and the number of nuetrons.
the total number of protons and neutrons in the nucleus.
The Atomic Mass is equal to the number of protons and electrons that an element has.
The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
The mass number of an element is equal to the sum of protons and neutrons in the nucleus, while the atomic number corresponds to the number of protons. These values can be found on the periodic table for each element.
The Atomic Mass of an element tells you what the mass of one mole (6.022 x 1023 atoms) of the element is. It sort of tells you the number of protons & neutrons in the atom, but that is not necessarily precise.
The number of protons, electrons, and neutrons:P
The atomic mass of an element is equal to the number of protons.
The element's average atomic mass.
An unbalanced equation is a chemical equation that does not have an equal number of atoms of each element on both sides of the equation. This means that the law of conservation of mass is not satisfied, as the total mass of the reactants does not equal the total mass of the products.
A balanced chemical equation shows that mass is conserved because the total mass of the reactants before a chemical reaction must equal the total mass of the products after the reaction. This is achieved by ensuring that the number of atoms of each element is the same on both sides of the equation.

An element's mass number tells us the total number of protons and neutrons in its nucleus. It helps to determine the element's atomic mass and differentiate it from other isotopes of the same element.
