How many neutrons are in Cl ion with a mass number of 35 and an atomic number of 17 with charge?

This means that there are two types of chlorine atoms; one with a mass number of 35 (17 protons + 18 neutrons) and one with a mass number of 37 (17 protons + 20 neutrons).

### How many protons are in a chlorine atom with a mass number of 35?

17 protons
An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus). Adding or removing a neutron from an atom’s nucleus creates isotopes of a particular element.

How many protons neutrons and electrons are in a chlorine atom with a mass number of 37?

Its nucleus contains 17 protons and 20 neutrons for a total of 37 nucleons….Chlorine-37.

## What is the mass of chlorine-35?

34.968852
Reference E95

Isotope Mass Spin
35Cl 34.968852 3/2
37Cl 36.965903 3/2

Why do 35 17 Cl and 37 17 Cl have the same chemical properties in what respect do these atoms differ?

In isotopes of 17Cl35 and 17Cl37 the atomic numbers are the same; hence, their electronic configuration remains the same, and so are their chemical properties. These differ only in physical contents and weights because neutrons contribute to the mass of an atom which is 35 and 37 in this case.

### What is the mass number of a chlorine atom with 17 protons and 18 neutrons?

An element with 17 protons will always be chlorine. However an element’s mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has a mass number of 35 which means it has 18 neutrons, it can also have a mass number of 37, which means it has 20 neutrons.

How many neutrons does chlorine 17 have?

A chlorine nucleus will contain: Number of protons Z = 17. Number of protons + neutrons A = 35. Number of neutrons N = 35 – 17 = 18.
