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.
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.
Identifying array-elements.
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 (:
Isotopes of uncharged elements have the same number of protons (which determines the element), but different numbers of neutrons. For example, carbon-12 and carbon-14 are isotopes of carbon with different numbers of neutrons but the same number of protons.
The atomic number of the isotopes of an element is identical; the mass number is different.
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 of elements are atoms with the same number of protons but different numbers of neutrons. This causes isotopes of the same element to have different atomic masses. Isotopes can be stable or unstable, with unstable isotopes undergoing radioactive decay.
Isotopes are atoms of the same element with different numbers of neutrons, while naturally occurring elements refer to all atoms of a particular element found in nature. Isotopes have the same number of protons but different atomic masses, whereas naturally occurring elements have consistent atomic masses based on the average of all isotopes present.
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.
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).
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.
