An atom of chlorine has 17 protons.
17 protons and 17 electrons in chlorine.
Atomic number is equal to the number of protons. The atomic number of chlorine is 17. So chlorine has 17 protons.
There are 17 protons in the nucleus of an atom of chlorine.
Chlorine has 17 protons.
There are 17 protons in Chlorine.
An atom of chlorine has 17 protons, while an atom of sodium has 11 protons. Therefore, an atom of chlorine has 6 more protons than an atom of sodium.
chlorine ion has 17 protons and 18 electrons.
The atomic number of chlorine is 17. So there are 17 protons in chlorine.
Calcium has 20 protons and Chlorine has 17, so 20+17= 37 protons.
The number of protons in an atom will always be the same as the atomic number, by which the periodic table is organized. So figuring out how many protons an atom has just becomes an exercise at reading the table. In this case, chlorine has an atomic number of 17.
17 +37=54 protons
