D Subshell
D all electrons? 3
In which of the following ions are the five D electrons in the outermost d subsection?
Mn2 +
Fe2 +
Re2 +
Y2 +
Rc2 +
Zn2 +
Ru2 +
Which of these ions has de-electrons in the outermost submarine?
Zn2 +
Fe2 +
y2 +
Nd2 +
Nc2 +
Hg2 +
Rc2 +
There can be many answers.
The configuration of Mn 2 + is 3d 5 (3d is the outermost submarine)
Re 2 + has 5d 5 configuration (5d is a subdomain of the outside)
Tc 2 + configuration is 4d 5 (4d is the outermost background)
Y 2 + 1-d electrons in 3d. Subs
Sc 2 + 1-d electrons in 4d subs
All this information is obtained from the knowledge of Table IC. You can find a copy of the ic table at the link below. Just click the element icon and then scroll down to find the element's electronics configuration. Transfer elements first lose electrons.
