57, the number of protons determines the elements number.
Lanthanum has 57 protons and 81-82 neutrons.
Each atom of Rubidium (Rb) has 37 protons.
Germanium has 32 protons.
It tells you (1) how many protons are in the element, and (2) what the element is since all atoms of an element will have the same number of protons.It's D. The number of protons in its atoms.It tells how many protons/electrons that element has.
Element X with 72 protons will have 72 electrons in a neutral state. The number of protons in an element is equal to the number of electrons in that element's neutral atom.
I dont think there is one.
54 Protons
Beryllium has four protons.
15 protons
Lanthanum has 57 protons and 81-82 neutrons.
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
The element that has half as many protons as zinc would be copper. Zinc has 30 protons, while copper has 29 protons. This means that copper has one less proton than zinc, making it the element with half as many protons.
The number of protons is the atomic number of the element.
neptunium has 93 protons.
Nickel has 28 protons.
Dubnium has 105 protons.
Nobelium has 102 protons.
