How does the metallic nature and the nonmetallic nature of elements in period 3 change from left to right?
Metallic character decreases as you go across any single period of the Periodic Table. This is because metals are characterized by their ability to lose electrons to form cations; the easier it is to do so, the more reactive a metal is. Non-metals are characterized by their ability to gain electrons to form anions; the easier to do so, the more reactive a non-metal is. As you go across any single period, elements gain an extra valency electron. This makes it harder and harder for those elements to lose their valency electrons, thus becoming more and more non-metallic.
What energy required to remove two valency electrons of a metallic atom?
This is the second ionization energy.
What is the valency for plumbic?
The valency for plumbic is +4. This means that plumbic compounds typically have a charge of +4.
What is the valency of bromide ion?
The valency of bromide ion (Br-) is -1.
How to find valency of PO4?
PO4^-3 is an ion.So its valency is -3

If an atom Y contains 6 electrons in the outer shell what will be its valency?
It needs two more electrons to complete octet and hence its valency will be two if it is non metallic.
What energy required to remove two valency electrons of a metallic atom?
This is the second ionization energy.
Which element is more metallic Al or Li or Na or Mg?
aluminium is more metallic than sodium because in metals the element which has the most electron in the outer most shell is more metallic . that means that Al is more metallic. sodium is reactive but aluminium is metallic. that'swhy its used for making aluminium wires ...
What is the valency of lithium?
The valency of lithium is 1. It has one valence electron in its outer shell.
What is valency of argon?
Its valency is 0.
What is valency of tungsten?
the valency is 4
What is the valency magnesium?
magnesium has a valency of 2
What is valency of nitrite?
the valency for nitrite is 5
What the valency for silver?
The valency of silver is typically +1. However, silver can also exhibit a valency of +2 in certain compounds.
What is the valency of Ferricyanide?
The valency of ferricyanide is -3. It contains one iron (III) cation with a valency of +3 and one cyanide anion with a valency of -1.
What is the Valency of sulfur?
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
