The electronic configuration for Cl atom is 1s2 2s2 2p6 3s2 3p5. It has one unpaired electron in the 3p shell, thus it is a free radical and very reactive. Hence chlorine does not exist in its atomic state as a Cl atom as it is too unstable.
An oxide ion (O^2-) has 0 unpaired electrons. It has a full outer electron shell with 8 electrons, fulfilling the octet rule.
Bromine is paramagnetic. This is because the 4p subshell has a value of 4p5. 5 electrons in a p subshell (which has space for 6), means the last electron is unpaired. The unpaired electron gives it the property of paramagnetism. Alternatively, Selenium is diamagnetic, as it has the outer subshell 4p4, meaning no electrons are unpaired.
A lone chlorine atom has 7 outer shell electrons, 1 electron short of a full outer shell of 8 electrons, which is stable. In order to achieve this full outer shell two chlorine atoms share a pair of electrons, with each atom contributing 1 electron to the pair. By sharing electrons in this manner the chlorine atoms achieve a full outer shell.
1 additional electron will give chlorine 8 in the valence. You can see in the Periodic table, that Chlorine is next to Argon ( 1 to the left of it) so it needs 1 more electron to have the same configuration as Argon.
Chlorine tends to attract electrons, as it has a high electronegativity. It has 7 valence electrons in its outer shell and tends to gain one electron to achieve a full outer shell, forming a chloride ion.
There are 0 unpaired electrons which would make it diamagnetic
Sodium has one outer ring electron, and chlorine has seven outer ring electrons. Sodium tends to lose its outer electron, while chlorine tends to gain an extra electron to achieve a stable electron configuration.
An oxide ion (O^2-) has 0 unpaired electrons. It has a full outer electron shell with 8 electrons, fulfilling the octet rule.
Chlorine has 7 electrons in its outer shell. It needs one more electron to achieve a full outer shell of 8 electrons, which is why chlorine typically gains an electron to form Cl- ion in chemical reactions.
One chlorine atom has 7 electrons in its outer shell, and sodium has 1 electron in its outer shell. Therefore, sodium can donate its electron to chlorine, forming a stable compound where chlorine has a full outer shell with 8 electrons.
A lone chlorine atom has 7 electrons in its outer shell or valence shell, with 3 pairs and 1 unpaired electron. This is an unstable configuration. A stable outer shell contains 8 electrons in 4 pairs. So, two chlorine atoms will form a covalent bond, each sharing its unpaired electron. This bond forms a full pair of electrons that is shared between the two atoms, effectively giving each atom a stable shell of 8 electrons.
Xenon has 0 unpaired electrons because it is a noble gas in group 18 of the periodic table and has a full outer electron shell.
Yes. That is true. There are 3 pairs of electrons, and 1 lone unpaired electron.
None - the electron goes from sodium TO the chlorine.
There are many elements which have no unpaired electrons in their outer shells. The Noble gasses all have closed shells of valence electrons. The alkali earth metals (Beryllium, Magnesium, Calcium etc) also have no unpaired electrons, although their outer shell is not entirely full.
chlorine has 6 electrons in the outer shell. although these have a special name, they are called valance electrons.
