Which Group of the Periodic Table can all have a valency of -1?
Halogens have a valency of -1.
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)
How do you find the valance of an element in the periodic table?
To find the valence of an element on the periodic table, look at the group number. Elements in group 1 have 1 valence electron, group 2 have 2 valence electrons, and so on. For transition metals, the valence can vary so it's determined by the charges in their compounds.
What group is the element helium located in on the periodic table?
Helium is located on the group 18 and period 1 on the modern periodic table.
How do find valency number?
To find the valency number of an element, look at the group number on the periodic table. For main group elements (groups 1, 2, 13-18), the valency is the same as the group number. For transition metals, the valency can vary and is usually determined by the charge of the ion formed by the element.

Valencies of all elements?
The valency of an element refers to the combining power of a given element. The valencies of all the elements is contained in the table of valencies. The valencies of the elements can be obtained by looking at the groups in the periodic table.
Is silicon a group 4 element?
No. In the modern periodic table, silicon (element 14) is a metalloid in group 14.Group 14 was previously known as "group IV" (A or B).

To find the valence of an element on the periodic table, look at the group number. Elements in group 1 have 1 valence electron, group 2 have 2 valence electrons, and so on. For transition metals, the valence can vary so it's determined by the charges in their compounds.
How do you find valency of any element?
The valence is the outer most shell and im assuming you need the amount of electrons on the outer most shell which would be the valence electrons. There can be no more than 8. The rule is 2-8-8. It could be done by referring to the group of that element in the periodic table.
What group is the element helium located in on the periodic table?
Helium is located on the group 18 and period 1 on the modern periodic table.
How do you find valency of an element?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
What is the valency of first and second group elements in the periodic table?
1 and 2 respectively
What is a group in a periodic table.?
A group in Periodic Table is the column of element in periodic table
