what are the first two quantum numbers for the electrons located in subshell 4d?

Each electron has its unique set of quantum numbers, which means that two electrons can share one, two, or even three quantum numbers, but never all four.

Now, you are given a  

4

d

orbital and asked to find how many sets of quantum numbers can describe an electron located in such an orbital, or, in other words, how many electrons can occupy a  

4

d

orbital.

So, the principal quantum number,  

n

, describes the energy level on which the electron is located. In this case, you have

n

=

4

→

the electron is located on the fourth energy level

The subshell in which the electron is located is described by the angular magnetic quantum number,  

l

, which for the fourth energy level takes the following values

l

=

0

→

the s-subshell

l

=

1

→

the p-subshell

l

=

2

→

the d-subshell

l

=

3

→

the f-subshell

Since you're looking for the d-subshell, you will need  

l

=

2

.

The specific orbital in which the electron is located is given by the magnetic quantum number,  

m

l

. For any d-subshell, the magnetic quantum number can take the values

m

l

=

{

−

2

,

−

1

,

−

0

,

+

1

,

+

2

}

Each of these five values describes one of the five d-orbitals available in a d-subshell.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
