Write the formulas for the analogous species of the elements of period 3; would you expect them to have the same hybridization at the central atom?

Explanation:

The elements belonging to third period which corresponds to B,C and N are Al, Si and P. All these elements in the third period tries to combine with four of hydrogen atoms and form an analogous species.

The formulae of these species are given as

All these species have a central atom which has four electron domain and the geometry of the electron domain is tetrahedral. The hybridization which corresponds to the geometry of tetrahedral electron domain is .

So have the same hybridization at the central atom such as .

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

it would be d. henry moseley

hope this !
