How many protons and neutrons and electrons does chlorine have?

How many protons and neutrons and electrons does chlorine 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.

What are the charges and relative mass of protons neutrons and electrons?

Subatomic particles

Subatomic particle Relative mass Relative charge
Proton 1 +1
Neutron 1 0
Electron 0.0005 -1

What is the relative atomic mass of chlorine?

35.453 u
Chlorine/Atomic mass

How many protons neutrons and electrons are in a chlorine atom with a mass number of 35?

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

What is the charge of chlorine?

Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.

How do you find the relative molecular mass of chlorine?

It is known that the chlorine molecule is diatomic – Cl2, then the relative atomic mass of the chlorine molecule will be equal to: Ar (Cl2) = 35,453 · 2 = 70,906 amu. The relative molecular mass of the chlorine molecule will be 70,906, and the molar mass: M (N2) = Mr (Cl2) · 1 mol = 70,906 g/mol or just 71 g/mol.

What is the number of electrons in chlorine ion?

18 electrons
2: The Formation of a Chlorine Ion. On the left, the chlorine atom has 17 electrons. On the right, the chloride ion has 18 electrons and has a 1− charge.

How many protons and neutrons does chlorine have?

What atom has 17 protons and 18 neutrons and 17 electrons? Name Chlorine Atomic Mass 35.453 atomic mass units Number of Protons 17 Number of Neutrons 18 Number of Electrons 17

What is the relative mass of an electron?

The relative mass of a neutron is 1. The relative mass of an electron is 1/1840 (accept 0). Consequently, what is the mass of an electron relative to a proton? One may also ask, do protons and neutrons have same mass? Protons are a type of subatomic particle with a positive charge.

What is the relative charge of a neutron?

Neutrons have a relative charge of 0. Since the neutron has an actual charge of 0C (it is neutral), we can simply give it a relative charge of 0. Notice that we drop the units of Coulombs, because relative charge does not have units. To summarise, the relative charges of protons, neutrons and electrons are as follows:

How is the atomic mass of chlorine determined?

Mass numbers of typical isotopes of Chlorine are 35; 37. Atomic mass of Chlorine is 35.453 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.
