To which period does an element belong if it has its 3d orbitals filled

1 answer:

3 0

fourth period

The third period is similar to the second, except the 3s and 3p sublevels are being filled. Because the 3d sublevel does not fill until after the 4s sublevel, the fourth period contains 18 elements, due to the 10 additional electrons that can be accommodated by the 3d orbitals.

Carbon (C): 1s(H)2s(I)2p(J)<br> What is H, I, and J equal?

Artemon [7]

Answer:

H =2; I = 2; J = 2

Explanation:

Carbon is element 6 in the Periodic Table.

Start at element 1 (H) and count from left to right until you reach element 6 (C).

You get the electron configuration

C: 1s² 2s²2p².

Thus,

H =2; I = 2; J = 2

Calculate the mass (in g) of 2.1 x 1024 atoms of W.

Monica [59]

Atomic mass W = 183.84 u.m.a

183.84 g ----------- 6.02x10²⁴ atoms
?? g ---------------- 2.1x10²⁴ atoms

2.1x10²⁴ x 183.84 / 6.02x10²⁴ =

3.860x10²⁶ / 6.02x10²⁴ = 641.30 g

hope this helps!
