How many electrons will a metal generally have in its outer energy level? 1 - 2 1 - 4 4 - 7 8

 The  electrons  that  metal   generally have  in its outer energy  level is  1-2

 Explanation

 In periodic table  most metal  are found in  group 1  and group 2.

Group 1   metals  has  1  electron  in their  outermost energy  level, while  group 2   metals has 2 electrons in their  outermost  energy level.

Therefore metal  have  generally 1-2  electron in its outer energy level.

I think 1-4

Explanation:

Since the metals occur earlier on in the table. That they’d have less in their outermost ring

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.
