all elements have the same amount of protons and neutrons. when they are not balanced e.g. there is an extra electron, they are no longer atoms they are ions.
Chlorine 37 has 17 electrons, assuming that it is not an ion. If chlorine 37 was existing as an ion then it would have 18 electrons. The isotope of the element does not affect the number of electrons it has.
17 same number as protons equal charge balance
17 electrons. The number of protons and electrons is always the same.
the atomic number
'17' Chlorine Atomic No, is 17. This means it is in position No. 17 in Periodic Table. It has 17 protons It has 17 electrons. NB Do NOT confuse with Atomic Mass of Chlorine. Chlorine has two common isotopes. One isotope has an atomic mass of 35 . That is 17 protons and 18 neutrons). The other isotope has an atomic mass of 37. That is 17 protons and 20 neutrons). For both isotopes the number of protons and electrons remains the same. An isotope is a different number of neutrons.
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
In an atom, there are the same amount of protons as electrons, if that's what you mean.
the number of protons and electrons are the same. on the Periodic Table of Elements you will see your element that you are looking for, then you will see there is a number under it. )ex. 9=flourine) that number is the number of protons. then, usually the number of protons, electrons, and neutrons are the same.
Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
An isotope
Chlorine exist as two isotopes(same number of electrons and protons but different number of neutrons), although there are traces of one more but we're not to sure. ~70% of Chlorine is Chlorine-35 which contains 17 electrons and 18 neutrons ~30% of Chlorine is Chlorine-37 which contains 17 electrons and 20 neutrons and ≤1% of Chlorine-36........
The two isotopes of chlorine are the same in that they have the same number of protons, which is the atomic number. The neutral atoms of each isotope also have the same number of electrons as protons. They differ in the number of neutrons.
