Halogens have a valency of -1.
All groups in the periodic table contain chemical elements.
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
No. Hydrogen, on a regular periodic table, is the first element in group 1, and it is part of the gas family.
Chromium, Molybdenum, Tungsten and Seaborgium are all in group 6 of the periodic table. They are all classified as metallic substances. They are all solids a 298 K.
all elements present in group 18 are gases.
Not sure what the command is but a characteristic which is common is that they have the same number of valency electrons.
Calcium, Magnesium, and Radium are all in group two of the periodic table.
A group is a column in the periodic table of elements.
group seven on the periodic table is the group where all it's elements end in 'ine' :) fluorine, bromine, etc.
Actually group 1 is ALL elements and so is the whole periodic table.
All groups in the periodic table contain chemical elements.
The alkali and alkaline earth and transitions are all groups of the Periodic Table ANOTHER POINT OF VIEW: A group or family is the vertical columns on The Periodic Table of the Elements.
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
Group 7 in the periodic table is less reactive.They are Manganese,Technetium,Rhenium and Bohrium.They all are transition metals.
No. Hydrogen, on a regular periodic table, is the first element in group 1, and it is part of the gas family.
they are all part of the Periodic Table:)
the most reactive (non-metals) group in the periodic table is GROUP 17+they are all reactive
