$\large \tt\underline\pink{Question}$

$\small{ \tt \red{What \: is \: the \: Atomic \: no \: , Symbol \: and \: Atomic \: weight \: of }} \\ \small{ \tt \red{Helium \: , Lithium , \: Boron \: , Carbon \: , Oxygen.}}$

$\large \tt \underline\red{Answer}$

$\tt \green{Helium} \\\tt\green{ \tt \implies \: Atomic \: No = 2} \\ \tt \green{ \tt \implies Atomic \: weight = 4.00} \\ \tt \green{ \tt \implies \: Symbol = He}$

─────────────────────

$\tt \pink{Lithium} \\\tt\pink{ \tt \implies \: Atomic \: No = 3} \\ \tt \pink{ \tt \implies Atomic \: weight = 6.94} \\ \tt \pink{ \tt \implies \: Symbol =Li }$

─────────────────────

$\tt \orange{Boron} \\\tt\orange{ \tt \implies \: Atomic \: No = 5} \\ \tt \orange{ \tt \implies Atomic \: weight = 10.8} \\ \tt \orange{ \tt \implies \: Symbol =B }$

─────────────────────

$\tt \red{Carbon} \\\tt\red{ \tt \implies \: Atomic \: No = 6} \\ \tt \red{ \tt \implies Atomic \: weight = 12.0} \\ \tt \red{ \tt \implies \: Symbol =C }$

─────────────────────

$\tt \blue{Oxygen} \\\tt\blue{ \tt \implies Atomic \: No = 6} \\ \tt \blue{ \tt \implies Atomic \: weight = 12.0} \\ \tt \blue{ \tt \implies \: Symbol = O}$
