Whatever row the element is in on the Periodic Table is the energy level, so the answer would be the metalloid in the third row, which is silicon (Si).
The energy level of an atom is occupied by electrons, which are negatively charged particles that orbit around the nucleus. The energy of these electrons depends on their distance from the nucleus and the specific quantum energy levels they occupy.
The period tells you how many energy levels an atom has.
It has 2 unpaired electrons and 8 empty electron levels.
Electrons are located in energy levels within the electron cloud.
electrons occupy sublevels in the order of increasing energy .
An atom's energy levels are occupied by electrons. Electrons occupy the energy levels, or electron shells, in order of increasing energy. The lowest energy level is filled first before electrons move to higher energy levels.

the period number tells which is the highest energy level occupied by the electrons
the period number tells which is the highest energy level occupied by the electrons
Electrons occupied certain discrete energy levels around the nucleus.

i don't the answer
An atom of oxygen has 2 energy levels that are occupied - the first energy level (K shell) can hold up to 2 electrons, and the second energy level (L shell) can hold up to 6 electrons. Oxygen has a total of 8 electrons.
the period number tells which is the highest energy level occupied by the electrons
In a neutral atom of calcium, there are 4 energy levels that are partially or fully occupied. Calcium has 20 electrons, distributed among the 4 energy levels with 2, 8, 8, and 2 electrons in each energy level, respectively.
The period number tell about the energy levels occupied by electrons
