Question

Thin sheets of element ‘X’ is used to pack food items & is both acidic & basic in nature. The atomic number of an element is 13 . (a)To which group & period does it belong to

Answer 1

Answer:

Explanation:

First of all, atomic number 13 ,is the biggest hint that tells us what the element is.

The answer, is Al or Aluminium.

Aluminium is used to cover food, in aluminium foils. It is amphoteric that is it is both acidic and basic in nature.

Element Name : Aluminium :-

• Electronic Configuration - 2,8,3
• Number of valence electrons - 3
• Number of shells - 3
• Period number - 3
• Group number - 10+3 = 13

So, the required answer is $\rm{Aluminium}$

Answer 2

Question :

⠀⠀⠀⠀⠀▪︎⠀Thin sheets of element ‘X’ is used to pack food items & is both acidic & ⠀⠀⠀⠀⠀⠀⠀⠀⠀basic in nature.

⠀⠀⠀⠀⠀⠀⠀⠀ The atomic number of an element is 13 .

⠀⠀⠀⠀⠀⠀⠀(a)To which group & period does it belong to

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

Given : A thin sheet element is used to pack food items & is both acidic & basic in nature & The atomic number of an element is 13 .

Exigency To Find : The name of an element & To which group & period does it belong to .

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

Given,

⠀⠀▪︎ Thin sheets of element ‘X’ is used to pack food items & is both acidic & basic in ⠀⠀⠀⠀⠀⠀nature & The atomic number of an element is 13 .

$\qquad \qquad \sf The \: name \:of\:element \:which \:symbolize \:\bf ‘X’ \sf \: in \:Question \:is \:\large{ \bf A}\small {\bf LUMINIUM \:}.$

⠀⠀⠀⠀⠀⠀EXPLANATION :

⠀⠀⠀⠀⠀⠀⠀⠀Aluminum Sheet :

• The Atomic no. of Aluminum is 13 .
• It is used to cover pack food items .
• It is both acidic & basic in nature .

Now ,

$\qquad \bigstar \qquad \sf Aluminium 's\:Period \:number \:is \: \bf 3 \:.$

$\qquad \bigstar \qquad \sf Aluminium 's\:Group \:number \:is \: \bf 13 \:\:[ \: Boron\:] \:.$

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

⠀⠀⠀⠀⠀⠀M O R E ⠀T O⠀ K N O W :

$\qquad \qquad \bigstar \:\:\bf {\Large{A} \small{LUMINIUM\:}: }$

• It's Electronic Configuration is 2 , 8 , 3 .
• No. of Valence is 3
• It's Boiling Point is 2743 K
• It's Melting Point is 933.47 K
