Elements in the same family have a similar chemical properties because they have the same number of valence electrons this statement is true about elements on a periodic table in the same group.
Hence, Option (B) is correct answer.
In periodic table there are 18 vertical column which is called groups which are arranged from left to right in the periodic table. In periodic table there are 7 horizontal rows which is called periods.
Elements in the same family or group have a similar chemical properties because they have the same number of valence electrons. In group one all the alkali metals have one valence electrons in the outermost shell.
Thus from the above conclusion we can say that Elements in the same family have a similar chemical properties because they have the same number of valence electrons this statement is true about elements on a periodic table in the same group.
Hence, Option (B) is correct answer.
