Protons = 17, electrons = 18

There are two isotopes differing in neutron number only :

  • Cl-35 (75%) having 35-17= 18 neutrons
  • Cl-37 (25%) having 37-17= 20 neutrons

How many protons and electrons are there in a chloride ion?

Chlorine has 17 protons and an atom of Chlorine would have 17 electrons. However a Chloride Ion will have one more electron ie 18 electrons and will be negatively charged.


If chlorine forms a 1- ion. How many electrons does a chloride ion have?

A chloride ion has gained one electron to become a Cl- ion, making it uncharged overall but with 18 electrons to match the 17 protons in its nucleus.


How many proton are in chloride ion?

Chloride ion like the chlorine atom has seventeen(17) protons. In an atom the number of protons and electrons is equal. However, in an ion the number of protons remains the same, BUT THE NUMBER OF ELECTRONS is different. So for chlorine atom there are 17 protons and 17 electrons. However, the chloride ion there are 17 protons and 18 electrons. This difference is indicated by 17(+) & 18(-) or (+)17 - 18 = -1 . So the chloride ion symbol is written as 'Cl^(-)'. The 'one' is never shown. NB A negative ion is given the name ' ANION;, NNB Do not confuse with 'Neutrons'. Different numbers of neutrons are referred to as ISOTOPES. Chlorine exhibits two principal isotopes. They are Chlorine-35 and Chlorine-37. Overall the proportions of these two isotpes is such that chlorine is given the atomic mass of 35.5. However, the number of protons remains the same at '17', and the number of electrons can still vary between the two isotopic atoms and ions.


Which ion has 17 protons 18 neutrons 18 electrons?

A chloride ion (of the isotope 35Cl) with a charge of -1. The 17 protons tell you its chlorine and since there is one more electron than proton it has a charge.


How many protons are in an oxide ion?

An oxide ion has 8 protons. This is because it is an oxygen atom that has gained 2 electrons to become negatively charged. The number of protons remains the same as the number of protons in a neutral oxygen atom.

Does a chloride ion have equal protons and electrons?

No. By definition an ion is electrically charged and so must have a different number of protons and electrons. A chloride ion has 17 protons and 18 electrons.


How many protons are in a ion with 86 electrons and a -1 charge?

A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.

What is the number of protons and electron in chrloride ion?

chloride ion is formed when chlorine atom adds one electron. Chloride ion thus has 17 protons and 18 electrons.


What is The number of protons in a chloride ion Cl- is?

A chloride ion (Cl⁻) has the same number of protons as a neutral chlorine atom, which is 17. This is because the number of protons, which defines the element, does not change when the atom gains or loses electrons to form an ion. Therefore, a chloride ion has 17 protons.


How many protons and electrons does chlorine have?

Chlorine has: 17 Protons 17 Electrons (in a neutral atom i.e. not an ion) (Isotope Mass Number - 17) is the number of Neutrons.

When table salt is dissolved in water the sodium ion donates one electron to the chloride ion. the chloride ion has 17 protons so it will have 16 electrons?

When table salt (sodium chloride) dissolves in water, sodium (Na) donates one electron to chlorine (Cl), forming sodium ions (Na⁺) and chloride ions (Cl⁻). Chlorine has 17 protons and, in its neutral state, also has 17 electrons. After gaining an electron from sodium, the chloride ion has 17 protons and 18 electrons, giving it a net negative charge. Thus, the statement about chloride having 16 electrons is incorrect; it should have 18 electrons after the electron transfer.


How many protons and electrons are there in a silver ion?

47 protons and 46 electrons.


How does an atom in chlorine -37 become a chloride ion with a -1 charge?

An atom of chlorine-37 has 17 protons and 17 electrons. To become a chloride ion with a -1 charge, it gains an additional electron, resulting in 17 protons and 18 electrons. This gain of an electron gives the ion a net negative charge of -1, making it a stable chloride ion (Cl⁻).
