1
Q
where are d-block elements found?
A
between group 2 and 3
2
Q
the highest energy sub-shell for d block elements is a
A
d sub-shell
3
Q
subshells in order of increasing energy
A
1s
2s 2p
3s 3p 3d
4s 4p 4d 4f
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 4d, 4f,
4
Q
s sub shell holds
A
2 electrons
5
Q
p sub shell holds
A
6 electrons
6
Q
d sub shell holds
A
10 electrons
7
Q
a transition element is a
A
d-block element
has an incomplete d sub-shell as a stable ion
8
Q
electrons occupy orbitals in order of
A
energy level
9
Q
how does the sub-shell energy level in the 3rd and 4th energy level overlap?
A
the 4s sub-shell fills before the 3d subshell
10
Q
why is 4s unusual
A
in shell 4 but has a lower energy than 3d shell 3
11
Q
electrons fill 4s before
A
3d
12
Q
electrons are lost from 4s before 3d
A
(it is of a lower energy level despite being in shell 4)
