Atomic radius of Ag is similar to

Options

A. `10.06 g cm^(-3)`
B. `5.3 g cm^(-3)`
C. `15.2 g cm^(-3)`
D. `6.5 g cm^(-3)`

Answer

A

Explanation

Density ` = (Z xx M)/(a^1 xx N_A)`
` = (4 xx 108)/((414.72 xx 10^(-10))^3 xx (6.022 xx 10^23))`
` = 10.06 g//cm^3`
`4r = sqrt2a`
` a= 2 sqrt2r`
= 414.72 pm
