Isotopes differ in the number of neutrons they possess.
two numbers with a product of 1 are called elements
Dalton said that all atoms of one element are identical. they are chemically identical but not identical in mass. he did not know of isotopes, which are chemically identical atoms with different numbers of neutral neutrons. ex: all carbon atoms act the same chemically but some mass at 12, others at 14.
Identifying array-elements.
Approximately, yes. But the mass number is an average of the masses of the isotopes of the element, weighted together according to their abundance. This averaging of different whole numbers results in the mass number not being a whole number.
The different names for Numbers are defined as Natural numbers, whole numbers , real numbers, decimal numbers, integers, rational numbers and irrational numbers.
Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons Neutrons (:
The isotopes of the same element has the same atomic number. But the mass number (atomic mass) is different.
The atomic number of the isotopes of an element is identical; the mass number is different.
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.
Because of the difference in mass number. Isotopes must have different numbers of neutrons.
They have different numbers of neutrons, which changes the atomic mass and nuclear properties.
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
It can if isotopes are present. They can contain different numbers of neutrons in the nucleus.

Elements can exist in the form of different isotopes. Isotopes of the same element have the same number of protons in their nuclei but have different numbers of neutrons. The first gives them the same atomic number and chemical properties while the second gives them different atomic weights.
No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).
Mass numbers of isotopes are different.
