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.
In the periodic table all of the familys (veritical collums) have the same number of valence electrons.
No. Hydrogen, on a regular periodic table, is the first element in group 1, and it is part of the gas family.
A column in the periodic table is called a group or a family. Elements within the same group share similar chemical properties due to having the same number of valence electrons. There are 18 groups in the periodic table.
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.
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.
The trend in valency of the periodic table generally increases from left to right across a period and decreases down a group. Elements on the left side of the periodic table tend to have lower valencies, while elements on the right side tend to have higher valencies. This is due to the number of valence electrons in the outer shell of the atom.
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.
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
Hydrogen, lithium, sodium, and potassium are all placed in the same column (Group 1) of the periodic table because they share similar chemical properties due to having one electron in their outermost energy level. This commonality makes them part of the alkali metal group, leading to their vertical alignment on the periodic table.
they are all part of the Periodic Table:)
Group 7 in the periodic table is less reactive.They are Manganese,Technetium,Rhenium and Bohrium.They all are transition metals.
