Four.
The atomic number is the number of protons, so 15.
The atomic number of iodine is 53 which means it has 53 protons.
If the atomic number is 118, the number of protons is 118. Atomic number is the number of protons in the nucleus of an atom. The elements are arranged in increasing order of atomic number. All of the atoms of an individual element have the same atomic number. Atomic number identifies an element.
An atom with an atomic number of 20 has 20 protons.
atomic number(Z) = no. of protons Detailed: The number of protons in a neutral atom is equal to the number of electrons in the same atom. And the number of electrons in an atom is equal to its atomic number.
An atom with an atomic number of four has four protons. The atomic number represents the number of protons in the nucleus of an atom.
Four.
Beryllium has four protons. 4 because that is atomic number
The atomic number is equal to the number of protons in the atom. Therefore, if an element has an atomic number of 24 (which in this case is chromium) then it has 24 protons. The mass number is the sum of the number of protons and neutrons.
27 protons atomic number = number of protons
The atomic number refers to how many protons in the nucleus and thus how many electrons are in orbit.
The atomic number IS the number of protons in the atom's nucleus.
Po has 84 protons because the atomic number is 84, and the number of protons is the same as the atomic number.
The atomic number is how many protons and electrons the element has. Hope this helps!!!
Atomic number describes about number of protons.It is equals to number of protons.
The atomic number IS the number of protons. if you are given the mass number, then subtract the number of protons from it.
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
