What is the charge of the nucleus?
What is the charge of the nucleus?
The nucleus of an atom carries a positive charge due to the presence of protons.
How many orbitals are in an 'f' subshell?
How many orbitals are in an 'f' subshell?
An 'f' subshell has 7 orbitals, each holding a maximum of 2 electrons, resulting in a total of 14 electrons.
What's the maximum number of electrons in the third energy level?
What's the maximum number of electrons in the third energy level?
The third energy level (n=3) has 3 subshells: 3s, 3p, and 3d. Each subshell can hold a specific number of electrons, resulting in a total capacity of 18.
