Question

Copper (Z=29) has same number of unparied electrons as a) Scandium (Z=21) b) Manganese (Z=25) c) Chromium (Z=24) d) Titanium (Z=22) plz ans fast if u want to get BRAINLIEST!!

Answer 1

$\huge\boxed{\fcolorbox{red}{blue}{ QUESTION }}$

Copper (Z=29) has same number of unparied electrons as :-

a)Scandium (Z=21)

b)Manganese (Z=25)

c)Chromium (Z=24)

d)Titanium (Z=22)

$\orange{\underline{\textit{\green{\bf{CONCEPT \:used:-}}}}}$

NO. of protron = No of electrons

VALENCY

$\orange{\underline{\textit{\blue{\bf{DEFINITION:- }}}}}$

It is the number of free electrons present in the outer most shell of the atom

$\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}$

COPPER BELONG TO 11 GROUP IT MEANS ITS HAS VALENCE ELECTRONS --> 7 OR WE CAN SAY ONE VALENCY

$\orange{\underline{\textit{\green{\bf{ELEMENT\: OF \: \: VALENCY:-}}}}}$

SO SAME NUMBER OF VALENCY IS IN

$\orange{\underline{\textit{\red{\bf{ SCANDIUM}}}}}$ $\underline{\blue{Z=21}}$
