The radius of an atom of element x is 1.2x10m the radius of the centre of the atom is 1/1 the radius of the atom calculate the radius of the centre of an atom of element x

Explanation:

Hello,

Based on the given information, the radius is computed via:

By assuming that the radius of the element is 1.2x10m, nevertheless, that is a pretty much big radius for an atom in meters, maybe a power is missing, but you can modify it by just including it in the aforesaid formula.

Best regards.

the answer to your question is c.

if you read the house of usher you should know that the house was haunted

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
