In this article, we shall examine the tendency im metallic character of 3rd row elements.

You are watching: Which of the following period 3 elements has the least metallic character


Metallic Character:

The propensity of an atom to lose electrons to kind positively fee ion is dubbed its metallic character or electropositive character. Frequently metals show luster and also are good conductors the heat and electricity.

Non-Metallic Character:

The propensity of one atom to gain electrons to type negatively fee ion is referred to as its non-metallic personality or electronegative character.

Factors affecting metallic and non-metallic characters:


*

As we move throughout the periodic table native left to right i.e. From salt to argon in the third period metallic personality decreases and also non-metallic personality increases. Sodium, magnesium, aluminium are usual metals. Silicon is metalloid. (weakly non- metallic). Phosphorous, Sulphur, Chlorine space non-metals. Argon is one inert gas.

Sodium is the many metallic element while chlorine is the most non-metallic element.Both the extreme elements sodium and also chlorine are exceptionally reactive. Argon is neither electropositive no one electronegative.

Scientific Reasons:

As us move across the regular table indigenous left to the right i.e. From salt to Argon in the third duration metallic character decreases and non-metallic personality increases.

As we relocate from left to ideal in the third period the atomic number walk on increasing. Thus as we relocate from salt to argon the nuclear charge increases and also from left come right extr electron is added to the very same i.e. Third orbit. Because of increase in the nuclear charge the attractive force on electron in outermost orbit increases and also thus the dimension of atom decreases.


As we relocate from left to ideal in the third duration the ionization enthalpy increases. Native left to right in the third-periodelectronegativity increases i.e. The propensity of shedding electrons to reduce and propensity of getting electrons increases. Together we relocate from left to right in the third-period variety of valence increases. Henceas us move throughout the routine table indigenous left come the appropriate i.e. From sodium to Argon in the third period metallic personality decreases and also non-metallic personality increases.

Sodium, Magnesium, Aluminium are common metals.

Metallic and non-metallic personalities of the elements depend on your atomic size, nuclear charge and ionization potential.Sodium, magnesium, aluminium have actually atomic numbers 11, 12, 13 respectively. Lock contain 1, 2, 3 valence electron in your outermost shell.

Compared to other elements in the 3rd row their atomic sizes are larger. Similarly, the nuclear charges are likewise less. Due to this attractive pressure on valence electron is less.Compared to other aspects in the third row your ionization enthalpies are lower.Thus the tendency of these aspects is to lose their valence electrons.Hence sodium, magnesium, aluminium are common metals.

Phosphorous, Sulphur, Chlorine room non-metals.


Metallic and also non-metallic characters of the aspects depend on their atomic size, nuclear charge and ionization potential.Phosphorous, sulphur, chlorine have actually atomic number 15, 16, 17 respectively. Lock contain 5, 6, 7 valence electron in their outermost shell.

Compared come other elements in the third row their atomic sizes are smaller. Similarly, the nuclear charges are additionally more. Due to this attractive force on valence electron is more.Compared to other aspects in the third row their ionization enthalpies are higher.Thus the propensity of these elements is no to shed their valence electrons yet to obtain electrons.Hence phosphorous, sulphur, chlorine are non-metals.

Argon is neither electropositive nor electronegative element.

Metallic and also non-metallic personalities of the elements depend on your atomic size, nuclear charge and also ionization potential.Argon has actually atomic number 18. It includes 8 valence electron in their outermost shell.Argon has actually completed octet and totally filled s and p orbitals hence it has actually the most stable electronic configuration in third-row elements which it will certainly not disturb by agree or shedding the electron.

Compared come other aspects in the third row its atomic sizes are larger however the impact of fill s and also p orbitals is dominating.Compared come other facets in the third row the ionization enthalpy is the highest.Thus the tendency of Argon to lose or get valence electrons is virtually absent.Hence Argon is no electropositive nor electronegative element.

Sodium is the many metallic element.


Metallic and non-metallic characters of the aspects depend on your atomic size, atom charge and also ionization potential.Sodium has atomic number 11. It contains 1 valence electron in that outermost shell.

Compared come other elements in the 3rd row the atomic dimension is larger. Similarly, the nuclear charge is also less. As result of this attractive force on valence electron is less.Compared come other aspects in the third row that ionization enthalpy is the lowest.Thus the propensity of salt is to shed its valence electron.Hence salt is the most metallic element.

Chlorine is the many non-metallic element.

Metallic and non-metallic characters of the facets depend on your atomic size, nuclear charge and ionization potential.Chlorine has atomic number 17. It has 7 valence electron in that is outermost shell.

Compared come other aspects in the third row that atomic dimension is the smallest. Similarly, the nuclear fee is also more. Because of this attractive force on valence electrons is more. Compared to other facets in the third row the ionization enthalpy is the highest. Thus the tendency of Chlorine is not to shed its valence electrons yet to obtain electrons. Hence Chlorine is the most non-metallic element.
