Is called an Isotope.
An isotope
An isotope.
Neutrons
The sum of the number of protons and the number of nuetrons.
well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
An atom of an element that differs in the number of neutrons compared with other atoms in the same element is called an isotope. Isotopes have the same number of protons and electrons but different numbers of neutrons, resulting in variations in atomic mass.
An isotope
This atom is called isotope.
An isotope differs from its parent element in the number of neutrons in its nucleus, which can affect its stability and properties.
the atom is an isotope
Atomic mass increases with the ordered placement of the element of the periodic table. Conveniently, the number of protons, nuetrons and electrons also increase with numbered order on the table. Every element is assigned a number. This number is equal to the number of protons, nuetrons and electrons. I believe it's the nuetrons that make up the mass of the element, but not sure!
Sodium is a metal element. Atomic mass number of it is 23.
add the number of protons and nuetrons together
An isotope.
The number of neutrons and protons together constitutes the mass number of a single isotope of an element.
An element can be identified by the number of protons in the nucleus of its atoms.
