Why is a chlorine ion not an argon atom?

Why is a chlorine ion not an argon atom?

Argon is a neutral atom with atomic number of 18. It has an electron configuration of 2 electrons in the first energy level, 8 in the second, and 8 in the third, for a total of 18 electrons. So when chlorine gets one more electron to fill that third level, it becomes a chloride ion with a net charge of -1.

Can chlorine become argon?

When chlorine gains an electron to become a chloride ion with a 21 charge, it ends up with the electron arrangement of argon.

Does the identity of a chlorine atom change to argon when it gains an electron?

Has the chlorine atom changed to an argon atom? Explain. No; the electron configurations of a chlorine ion and an argon atom are the same, but the chlorine ion still has 17 protons and retains its identity as chlorine.

What is wrong with this statement when a chlorine atom gains an electron it becomes an argon atom?

What is wrong with this statement? “When a chlorine atom gains an electron, it becomes an argon atom.” An atom does not change into another atom. When the chlorine atom gains an electron, it has the same electron configuration but it is still a chlorine atom.

What does a chlorine atom have to do to have the same configuration as argon?

In terms of energetics, it takes much less energy to lose two electrons than to gain 6. By the same token, chlorine will be isoelectronic with Argon if it gains one electron, but will have to lose seven electrons to be isoelectronic with neon.

Is a chlorine ion the same as argon?

yes we can call chlorine as a argon atom. Explanation: The electronic configuration of chloride ion is same of the argon electronic configuration.As the chloride ion cl^- gains 1 electron to attain the stability. ∴HENCE,we can say chloride ion as a argon atom.

Has the chlorine atom changed to an argon atom?

Has the chlorine atom changed to an argon atom? No; the electron configurations of a chlorine ion and an argon atom are the same, but the chlorine ion still has 17 protons and retains its identity as chlorine.

When a chlorine atom gains an electron it becomes what?

Chlorine gains an electron, leaving it with 17 protons and 18 electrons. 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.

When a chlorine atom gains an electron what does it become?

Is chlorine ion bigger than argon?

Cl ion is bigger than Ar atom because simple Cl atom has 7 electrons in its outermost shell but when it attain a noble gas configuration it has 8 e- in its outermost orbit so the size of this atom increases as it attain noble gas configuration.

Why does chlorine gain one electron?

Chlorine (Cl) in its lowest energy state (called the ground state) has seven electrons in its outer shell. 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.

When chlorine atom get one electron and form chlorine ion the number of electron it has same to?

has
The chlorine atom, which has a high electronegativity, gains an electron and is converted into a chloride ion that has the same electron configuration as argon (1s2 2s22p6 3s23p6). The chloride ion has a − 1 charge because there are 17 protons in the nucleus, but there are 18 electrons around the nucleus of the ion.

How did argon and chlorine get their names?

Chlorine derived its name from from the Greek word chloros, meaning ‘greenish yellow’ The element Argon was discovered by Lord Rayleigh in year 1894 in United Kingdom. Argon derived its name derived its name from from the Greek word argos, meaning ‘idle’ Presence: Abundance in Nature and Around Us

Why do we use configuration notation for chlorine?

Video: Chlorine Electron Configuration Notation. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.

How many electrons does a chlorine atom have?

In order to write the Chlorine electron configuration we first need to know the number of electrons for the Cl atom (there are 17 electrons).
