What is the Lewis dot structure for the HYDRIDE ion?
A)H:-
B)H+
C)H'
D)H3O+
E)none
It's hard for me to read the dots but I THINK answer a) looks like this?
H:-
If so that is the Lewis dot structure for the hydride ion
not D, that's hydronium, not b, that's just hydrogen.. so idk, a or c.. the other thinks its c so lets go with that
To determine the Lewis dot structure for the hydride ion (H-), we need to understand the concept of Lewis dot symbols or Lewis structures.
Lewis dot structures represent the valence electrons of atoms within a molecule or ion. Valence electrons are the electrons in the outermost energy level of an atom and are responsible for the atom's chemical behavior.
Hydrogen (H) is in Group 1 of the periodic table, which means it has one valence electron. The hydride ion (H-) has gained an additional electron, bringing its total number of valence electrons to two.
To represent the hydride ion using Lewis dot notation, we place the hydrogen atom symbol (H) and use dots to represent the valence electrons. Since hydrogen only has one valence electron, we place a single dot next to the hydrogen atom to represent this electron.
Therefore, the Lewis dot structure for the hydride ion (H-) is:
H:-
So, the correct answer is A) H:-.
