# How many electrons and neutrons are in chlorine?

## How many electrons and neutrons are in chlorine?

Chlorine is an element with unique properties 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 and protons does chlorine have?

17
Chlorine/Atomic number

Do all chlorine atoms have 17 neutrons?

All atoms of chlorine (Cl) have 17 protons, but there are chlorine isotopes with 15 to 23 neutrons. Only two chlorine isotopes exist in significant amounts in nature: those with 18 neutrons (75.53% of all chlorine atoms found in nature), and those with 20 neutrons (24.47%).

Why does chlorine have 18 neutrons?

Atoms and isotopes 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.

## Why does chlorine have 17 electrons?

The electrons like to be in separate shells/orbitals. Shell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons. That means there are 17 electrons in a chlorine atom.

### What isotope has 17 protons and 18 neutrons?

Chlorine-35
Chlorine-35 has 17 protons and 18 neutrons.

What has 17 protons and 18 neutrons?

chlorine atom
Every chlorine atom has 17 protons in its nucleus. Not all atoms of chlorine have the same number of neutrons, however. Some atoms of chlorine have 18 neutrons in their nuclei.

What has 18 protons and 17 neutrons?

Name Chlorine
Atomic Mass 35.453 atomic mass units
Number of Protons 17
Number of Neutrons 18
Number of Electrons 17

## Why does chlorine have 2 isotopes?

Adding or removing a proton from an atom’s nucleus changes that atom’s atomic number and creates a different element. Chlorine-35 and chlorine-37 are both isotopes of the element chlorine. Since all atoms of chlorine contain 17 protons, chlorine-35 and chlorine-37 differ in the number of neutrons each one has.

### What is the difference between the two isotopes of chlorine?

Chlorine-35 and chlorine-37 are both isotopes of the element chlorine. 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).

What has 4 protons and 3 neutrons?

Lithium
Lithium, for example has three protons and four neutrons, leaving it with a mass number of 7.

What has 18 protons and 22 neutrons?

Argon
Given the number of protons is \[18\]. So, the atomic number is also \[18\], and the element with atomic number \[18\] is Argon with the symbol \[Ar\]. Now we need to find the mass number of Argon. Since, a neutral atom of argon also has 22 Neutrons.

## How many protons and electrons does chlorine have?

The atomic number of chlorine is 17; thus, it has seventeen protons and seventeen electrons. Its electron configuration is written as 1s 2 2s 2 2p 6 3s 2 3p 5. Since the p sub level should have 6 electrons to obtain the Argon noble gas electron configuration, chlorine has the ability to attract an electron.

### What gas element has 48 neutrons?

The fourth noble gas of atomic number 36 and symbol Kr is known as Krypton.It contains 36 protons and electrons each and 48 neutrons. Krypton with atomic mass 83.798 has a set of isotopes in large number. It was derived from the Greek word ‘Kryptos’ which mean hidden.

What element has 5 neutrons?

The number of neutrons corresponding to the most common isotope of the element is in bold type. All beryllium atoms have 5 neutrons in the nucleus and all ﬂuorine atoms have 10 neutrons. Most hydrogen atoms have no neutrons but the deuterium isotope (H-2) has 1 neutron and the tritium isotope (H-3) has 2 neutrons.

What transition element has 25 electrons?

Manganese is the first element in the seventh column of the periodic table. It is classified as a transition metal. Manganese atoms have 25 electrons and 25 protons with 30 neutrons in the most abundant isotope.
