Group 1a in Periodic Table contains hydrogen and the alkali metals. the question does not specify which three out of the seven elements in the group are being referred to. The metals all ionise to form M+ ions e.g. Li+, Na+, K+ etc. Hydrogen is the odd one out- whilst it does lose an electron to form H+ (a bare nucleus with a charge of +1) it can also gain an electron (to achieve the noble gas configuration of He, helium) forming the H- hydride ion.
They have the same number of valence electrons and similar chemical properties.
All the columns have same number of valence electrons. They possess similar chemical properties.
The 8th column in the periodic table - those atoms with a completed valence orbits.
Semi-metals
A group in periodic table is the column of element in periodic table
Elements in the same column have the same number of valence electrons, and form ions with the same charge.
Silver is in column 11 in the most common wide form periodic table.
Yes. Atoms get larger as they move downward in a column of periodic table. This is because of increase in number of shells down the group.
They have the same Valency
The 8th column in the periodic table - those atoms with a completed valence orbits.
The noble gases, column 18 in the most common modern periodic table.
A group in Periodic Table is the column of element in periodic table
Chemicals in a column, or "group" have similar chemical properties.
Beryllium is in column 2 of a wide form periodic table and column II(A) of a narrow form periodic table.
A column, also called group, is a vertical line on the periodic table.
a column or family on the Periodic Table
All of the elements in column 18 of the periodic table are noble gases. This means their outer electron shells are completely full and in most cases are inert.
They are the same
That column contains the Noble Gases (He, Ne, Ar, Kr, Xe, Rn).
