What is the 113th element in chemistry?

Answer 1

Valence electrons are the outermost electrons. If you look at the Periodic Table, d- and f-orbitals always fill after s- and p- electrons from outer shells do. For instance, the 3d orbitals start filling after the 4s, and the 4f orbitals start filling after the 6s's. So valence electrons will always just include s- and p- electrons. For Ununtrium (element 113), the electron configuration is: [Rn] 7s2 5f14 6d10 7p1 The outermost (valence shell) is the 7th shell, and there are two electrons in the 7s orbital and 1 electron in the 7p orbital. So there are three valence electrons in element 113.

Answer 2

The element would have to gain 2 electrons to complete its outermost shell. Therefore its valency will become 2-. The element you are talking about is Ununhexium. The Symbol Uuh. Answer; Uuh2- (2 is superscript).

Why? If you look at the orbitals of the elements( s, p, d, f).

S orbital contains 2 electrons. P contains 6. D contains 10. F contains 14.

The large number before the type of orbital in the diagram below indicates the energy level.

1s =2 electrons

2s 2p = 8 electrons

3s 3p 3d = 18

4s 4p 4d 4f =32

5s 5p 5d 5f =32

6s 6p 6d =18

7s 7p =8

total of 118 electrons.

So 116-2-8-18-32-32-18=6

The last orbital is 7p so 8 electrons fit into that orbital. 8-6=2 [der ;) ]

The element gains to electrons to fill the outermost shell and the valency becomes 2-.

Hope that helped (:

Answer 3

[Rn] 5f14 6d10 7s2 7p1
