| Energy Level | Number of Electrons |

| K | 2 |

| L | 8 |

| M | 9 |

| N | 2 |

The nucleus is located at the center of the atom. The electron shells are labeled K, L, M, and N, starting from the innermost shell. Each shell can hold a maximum number of electrons, as indicated in the table. The electrons are arranged in subshells within each shell. The s subshell can hold a maximum of 2 electrons, the p subshell can hold a maximum of 6 electrons, the d subshell can hold a maximum of 10 electrons, and the f subshell can hold a maximum of 14 electrons.

In scandium, the electrons are distributed as follows:

* K shell: 2 electrons in the 1s subshell

* L shell: 8 electrons in the 2s and 2p subshells

* M shell: 9 electrons in the 3s, 3p, and 3d subshells

* N shell: 2 electrons in the 4s subshell

The Bohr model of scandium shows the arrangement of electrons in the atom. The electrons are arranged in shells around the nucleus, with each shell having a specific energy level. The electrons in the outermost shell are the most loosely bound to the nucleus and are therefore the most reactive.
