1. it takes: ____ electrons to fill the 6d subshell of an atom.

2. It takes _____ electrons to fill the n=6 shell of an atom.

I thought it was 22 and 72?

The maximum number of electrons in ANY d orbital is 10.

The maximum number of electrons in any shell is 2N^2. 72 is right but 22 is wrong.

1. The 6d subshell can hold a maximum of 10 electrons. Each orbital in the subshell can hold 2 electrons, and there are 5 orbitals in the 6d subshell. Therefore, it takes 10 electrons to fill the 6d subshell of an atom.

2. The n=6 shell consists of multiple subshells, including the 6s, 5d, 4f, and 3p subshells. The 6s subshell can hold a maximum of 2 electrons, the 5d subshell can hold a maximum of 10 electrons, the 4f subshell can hold a maximum of 14 electrons, and the 3p subshell can hold a maximum of 6 electrons. Adding these together, it takes a total of 2 + 10 + 14 + 6 = 32 electrons to fill the n=6 shell of an atom.

So, the correct answers are:
1. It takes 10 electrons to fill the 6d subshell of an atom.
2. It takes 32 electrons to fill the n=6 shell of an atom.

To determine the number of electrons needed to fill a specific subshell or shell of an atom, we need to understand the rules for electron filling. The electron filling pattern follows the Aufbau principle, Pauli exclusion principle, and Hund's rule.

1. Filling the 6d subshell:
The 6d subshell has five orbitals. According to Hund's rule, each orbital is singly occupied before pairing occurs. So, the maximum number of electrons the 6d subshell can hold is 5 x 2 = 10.

2. Filling the n=6 shell:
The n=6 indicates the principal energy level, also known as the shell. To find the number of electrons required to fill this shell, we should consider the maximum number of electrons that can be present in any given shell. According to the formula 2n^2, where n is the principal quantum number, the maximum number of electrons in the n=6 shell is 2 x 6^2 = 72.

Therefore, your initial assumption is correct. It takes 10 electrons to fill the 6d subshell and 72 electrons to fill the n=6 shell of an atom.
