atomic number
protons in its nucleus, which defines the element.
The number of protons is also the same as the atomic number.
atomic number
The atomic number of an element is the number of protons in the nuclei of its atoms. Each element has a unique atomic number.
The number of protons an atom has depends on which element it is. Every element has a different number of protons. And within each element, there will be a different number of neutrons, creating isotopes.
The atom's atomic number is equal to the number of protons in its nucleus.For example, an element with 19 protons in its nucleus is Potassium (K), the 19th element on the periodic table.
Each element has a unique number of protons in the nucleus of their atoms.
The number of electrons outside the nucleus depends on the atomic number of the element. For neutral atoms, the number of electrons is equal to the number of protons in the nucleus to maintain a balanced charge.
Depends on the element. Every element has a unique number of protons within the nucleus of each atom. For example, Hydrogen atoms all have one proton in the nucleus. Take a look at the atomic number of an element on the period table. This number tells you how many protons are located in each atom of the material.
The number of protons in an atom is determined by its atomic number, which is unique to each element. The atomic number represents the number of protons in the nucleus of an atom. It is the key characteristic that defines the identity of an element.
Each atom of one specific element has the same number of protons. For example, Helium has 1 proton in every atom's nucleus. To find how many protons are in an elements atoms nucleus, look at the elements atomic number on the Periodic Table.
It is the number of protons in the nucleus of the atom and it determinnes many properties of the atom. The atomic number is also the number of electrons and is a constant for every element
