Gallium is a non metal element. Mass number of it is 70.
Gallium is a meta element. Atomic number of it is 31.
There are two stable isotopes of gallium: gallium-69 and gallium-71. Additionally, there are several radioactive isotopes of gallium, but they are unstable and decay over time.
Yes, gallium does have naturally occurring isotopes. The most common stable isotopes of gallium are gallium-69 and gallium-71, with gallium-69 being more abundant at about 60% and gallium-71 about 40%.
The mass number of an element is the total number of protons and neutrons in its nucleus. Gallium-72 has 31 protons (the atomic number of Gallium) and 41 neutrons, giving it a mass number of 72.
Gallium is a non metal element. Atomic mass of it is 70.
The one you are thinking of is probably the trefoil symbol, three black foils on a yellow background. See link below
72
That would depend on the isotope of Gallium. Elements can have many different isotopes, which are alternate forms of an element which contain the same number of protons, but a different number of neutrons. Gallium has two primary isotopes, one which has 38 neutrons, and another which has 40 neutrons.
An isotope is named for its mass number, so gallium-71 has a mass number of 71.
isotopes of the same element have different mass number
They are called as isotopes in which mass number differ by emmision of radiation
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
