# What is the electrical charge of an atom of chlorine?

## What is the electrical charge of an atom of chlorine?

Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion.

### How many electrons are in an electrically neutral atom of chlorine?

17 electrons
A neutral chlorine atom, for example, contains 17 protons and 17 electrons. By adding one more electron we get a negatively charged Cl- ion with a net charge of -1.

How many neutrons does a chlorine ion with a charge have?

Chlorine has an atomic number of 17 and an atomic mass of 35.45, meaning that an atom of chlorine consists of 17 protons, 17 electrons, and 18 neutrons.

How many neutrons are in a chlorine atom?

17Chlorine / Atomic number

## How do you find the charge of Cl?

Chlorine has 17 electrons (a charge of -17) and 17 protons (a charge of +17), so the overall charge is zero. Once the chlorine gains an electron, however, the total just becomes -1 since there are now 18 electrons and still 17 protons. As a result chlorine is a negative charged ion. It is written as: Cl-.

### What ion charge does chlorine form?

(–1)
Again, it is more energy-efficient for chlorine to gain one electron than to lose seven. Therefore, it tends to gain an electron to create an ion with 17 protons, 17 neutrons, and 18 electrons, giving it a net negative (–1) charge. It is now referred to as a chloride ion.

Why is chlorine atom electrically neutral?

Chlorine atomic number is 17 so its number of protons = number of electrons = 17 so chlorine atom is electrically neutral.

How many neutrons does this atom have when neutral?

An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 – 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons.

## How many protons neutrons and electrons are in chlorine 37?

Chlorine atom, 35Cl 17 17
Chlorine atom, 37Cl 17 17

### How many protons neutrons and electrons are there in chlorine?

For example, every chlorine atom has 17 electrons and 17 protons; its atomic number is 17. However, three out of four chlorine atoms weigh 35 amu (17 protons and 18 neutrons) and the fourth weighs 37 amu (17 protons and 20 neutrons). These are the isotopes of chlorine.

How many electrons does chlorine atom have?

2: The Formation of a Chlorine Ion. On the left, the chlorine atom has 17 electrons.

How do you find the neutrons of chlorine?

Therefore we can subtract the number of protons from the atomic mass number in order to work out the number of neutrons. Chlorine has a mass number of 35, minus the 17 protons means that chlorine has 18 neutrons.

## How many neutrons can be found in chlorine?

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. The different types of chlorine are called isotopes of chlorine. Isotopes are forms of an element that have the same number of protons but different numbers of neutrons.

### How many electrons are shared by chlorine?

There are two electrons shared by the two Cl atoms so there is a single bond between the Cl atoms. Each chlorine has 7 valence electrons plus the one it is sharing for a total of 8 valence electrons. So each Cl atom will have 8 valence electrons as a result of sharing. This is the rule of octet.

How many neurons does a chlorine atom have?

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 chlorine-35?

Chlorine-35 is composed of 17 protons, 18 neutrons , and 17 electrons. Chlorine-37 is composed of 17 protons, 20 neutrons, and 17 electrons. Chlorine-36 is composed of 17 protons, 19 neutrons, and 17 electrons.
