Nice Question !

Solution 6:

(a). Copper(Cu)

(b). CuSo4

(c). Y= Copper Hydroxide Cu(OH)2 [blue precipitate.

(d). CuSo4(aq) + 2NaOH(aq)--> Cu(OH)2(s) + Na2SO4(aq)

Solution 7:

In the particular group Alkali metal in group like 1st group.. have only one valence electron in it's Outermost shell. Thus every elements of the group possess same properties.

Solution 8:

In the same period valence electrons of every elements differ from each other. That's why elements in the same period differ in chemical properties.

Hope You Understand :)

Thank You !
