How many unpaired electrons are present in each of these species?

(a) 1s22s23p1

ground-state

whats the config for this?

I don't understand the second sub post. The number of unpaired electrons is 1; i.e., the 3p1.

To determine the number of unpaired electrons in the ground state configuration of the species 1s22s23p1, we need to analyze the electron configuration.

The electron configuration 1s22s23p1 represents the electron arrangement in the outermost energy level of the atom. In this case, the outermost energy level is the 3rd energy level (3p).

The 3rd energy level can hold a maximum of 8 electrons (2 electrons in the 3s sublevel and 6 electrons in the 3p sublevel).

According to the electron configuration, we have 1 electron in the 3p sublevel. This electron is unpaired, meaning it does not have a partner with opposite spin.

Therefore, there is 1 unpaired electron in the species with the electron configuration 1s22s23p1.

To determine the number of unpaired electrons in the given electron configuration (1s22s23p1), we need to understand how electrons are filled in atomic orbitals.

In this electron configuration, we have a total of 4 electrons. The 1s orbital can hold a maximum of 2 electrons, the 2s orbital can also hold a maximum of 2 electrons, and the 2p orbital can hold a maximum of 6 electrons.

The electron filling pattern follows the Aufbau principle, which states that electrons fill the lowest energy orbitals first. Therefore, in this case, we fill the 1s orbital with 2 electrons, followed by the 2s orbital with another 2 electrons.

Now, let's look at the last electron in the 2p orbital. Since the 2p orbital can hold a maximum of 6 electrons, we have 3 orbitals to accommodate those 6 electrons (2pX, 2pY, and 2pZ). Thus, we can determine that the electron in the 2p1 state occupies one of those three orbitals.

An unpaired electron refers to an electron that occupies an orbital by itself, without a paired electron. In this case, since we have 3 2p orbitals and only 1 electron in the 2p1 state, we can conclude that there is 1 unpaired electron in the given species.
