An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
If an atom has 7 electrons, then in the second energy level there would be 1 electron. The second energy level can hold a maximum of 8 electrons.
There are 8 electrons in the third energy level of a calcium atom.
There are two electrons in the second energy level of a boron atom.
Yes, electron sharing typically occurs in the outermost energy level, known as the valence shell. This is because atoms strive to fill their valence shell to achieve stability by completing their octet (8 electrons for most elements).

valence electrons are the electrons in the outermost energy level
The electrons on the outermost energy level of the atom are called valence electrons.
The third energy level of an atom can hold a maximum of 18 electrons. This level consists of one 3s orbital (2 electrons), three 3p orbitals (6 electrons), and five 3d orbitals (10 electrons).
The valence electrons.
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 outermost energy level of an atom is known as the valence shell. In general, the valence shell can hold up to 8 electrons. However, the number of electrons that actually fill the valence shell can vary depending on the element and its position in the periodic table.
Electrons found in the outermost energy level of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms, which determines the atom's reactivity and behavior in chemical reactions. The number of valence electrons an atom has contributes to its position in the periodic table and helps predict its chemical properties.
