In this activity, you will construct a periodic table to see how valence electrons correspond with certain sections of the table. the following is a portion of the periodic table that includes the first 18 elements. for each of these elements, the number of electrons present in each level is shown. however, four of these values have been entered incorrectly

select the four values in the table

heat or electricity in the atmosphere- c.

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.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

you need to have a picture of the atom that way we can answer it
