it is in the second period. so boron has 2 energy levels
a sulfur atom has 3 energy levels. 2 on the first. 8 on the second and 6 on the third
There are two energy levles in a Boron! :) Happy to help!
The first energy level has a maximum of two valence electrons. The second and third energy levels have a maximum of 8 valence electrons.

There are 2 energy levels in a Carbon atom. The first energy level consists of '1s' orbital, and the second energy level consists of the '2s' orbital and the '2p' orbital.
An atom of calcium in the Bohr model has four energy levels. These energy levels are designated by the quantum numbers n=1, 2, 3, and 4, corresponding to the first, second, third, and fourth energy levels, respectively.
An electrically neutral sodium atom has 11 electrons. These electrons occupy different energy levels or shells around the nucleus. Sodium has 3 electron shells or levels: the first energy level can hold up to 2 electrons, the second energy level up to 8 electrons, and the third energy level up to 1 electron.
Carbon has 2 energy levels. There are 6 electrons, 6 protons, and 6 neutrons.
Bromine has FOUR energy Levels.
Arsenic has 8 levels of energy.
