b. number of electrons
c. atomic radius
d. electronegativity
12 CA 1 Which of the following elements can form a covalent (molecular) bond with nitrogen?

helloi think dog cat bunny dog cat bunny dog cat bunny

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

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

10

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.

your answer is c) plasma
