I am doing this in science. Metals tend to lend electrons. Which means metals usually form large molecules
Group number 17 of the periodic table is a poor conductor because all are non-metals and diatomic molecules.
Group 18
a group that forms anions with a -1 charge
-SH
Group 18 (noble gases), because there outer energy level is full
The elements of V- A group of periodic table form three covalent bonds as Nitrogen forms NH3 and phosphorus forms PH3.
Bromine belongs to group-17. When it gains one electron, it forms bromide ion.
Normally non-metals but there are exceptions
A column is known as a group in periodic table. There are 18 groups in the modern setting of periodic table. Elements in the same group usually share same chemical properties and striking physical characteristic trends.
A group in Periodic Table is the column of element in periodic table
Chlorine is in Group 17 of the Periodic Table.
They are usually called alkaline earth metals.
