How man valence electrons does lithium?
in modern periodic table the elements are arranged in groups according to their valency . valency increases from 1 to 4 and then decreases from 4 to 0. thus as lithium belongs to third group its valency is 3
How do you take out valency an element?
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
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 platinum?
Possible valences are (+1), +2, (+3), +4, +6
How metallic and nonmetallic character is related to valency?
Metallic and nonmetallic character is closely related to the valency of elements. Metals typically have low valency (1-3) and tend to lose electrons easily, exhibiting metallic characteristics such as conductivity and malleability. In contrast, nonmetals usually have higher valencies (4-7) and tend to gain or share electrons, leading to their nonmetallic properties like poor conductivity and brittleness. As a general trend, elements with lower valency are more metallic, while those with higher valency are more nonmetallic.
What is the valency of carbon?
The combining power of carbon is 4. This means that each carbon atom can form 4 bonds.
What the valency of So2 and So3?
The valency of SO2 is 4, while the valency of SO3 is 6. The valency of an atom is the combining power of an element, which indicates the number of bonds it can form with other elements.

What is valency of tungsten?
the valency is 4
Which element has 4 and 6 valency?
Carbon has a valency of 4, while sulfur has a valency of 6.
Valency of titanium?
Titanium has (max.) 4 valence electrons, possible oxidation states: +4, +3, +2, (+1, rare).
What is valency of germanium?
The valency of germanium is four. This means that germanium typically forms covalent bonds with other elements by sharing four electrons in order to achieve a stable electron configuration.
What is the valency of silicate ion?
The valency of the silicate ion is -4, meaning it has a charge of -4. This is because the silicate ion is made up of one silicon atom (which has a valency of +4) and four oxygen atoms (each with a valency of -2).
How do you learn symbols and valencies?
You need to learn the symbols for the elements I am afraid. Start using a Periodic table (see the links below).You could also learn the valencies but if you know the periodic table and understand why elements appear where they do, you can work out the likely valencies from the positions of the elements in the table - they are where they are for a reason!You must ask your chemistry teacher to explain this reasoning to you - it should form part of your lessons.This will helpGroup number 1 = Valency 1group number 2 = valency 2group number 3 = valency 3group number 4 = valency 4group number 5 = valency 3group number 6 = valency 2group number 7 = valency 1group number 8 = valency 0 (noble gases, nonreactive)
What is the valency of silicate?
the valency of silicate ion is 4-
