1) Assinale a alternativa correta: A ligação covalente ocorre entre átomos com tendência de: A - Receber elétrons
B - Doar elétrons

2) Considere o elemento cloro formando compostos com, respectivamente, hidrogênio, Carbono, sódio e cálcio

A) Com quais elementos o cloro forma compostos covalentes ? Dê a fórmula de Lewis e estrutural desses compostos

B) Com quais desses elementos o cloro forma compostos iônicos ? Dê a fórmula de Lewis e a iônica desses compostos

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.
