An element with 2 energy levels and 2 electrons in the outer layer is beryllium (Be). Beryllium has an atomic number of 4, with 2 electrons in the first energy level and 2 electrons in the second energy level, making it a neutral atom.
A neutral neon atom has 8 electrons in its outer shell. Neon has a total of 10 electrons, with 2 in the inner shell and 8 in the outer shell.
The overall charge of a beryllium atom is neutral, meaning it has the same number of protons (+) in the nucleus as it does electrons (-) surrounding the nucleus. Beryllium has 4 protons and typically 4 electrons, resulting in a neutral charge.
There are two electrons in the 4s orbital of the neutral atom with the ground state outer electron configuration of 4s2.
A neutral atom of oxygen typically has 6 electrons in its outer orbit, which is the second energy level. This gives oxygen a full outer shell, providing stability.
Beryllium typically has 4 electrons in total. It has 2 electrons in its inner shell and 2 electrons in its outer shell.
A beryllium ion, like Be2+, has lost two electrons compared to a neutral beryllium atom. A neutral beryllium atom has 4 electrons, with 2 in the inner shell and 2 in the outer shell. When it loses 2 electrons to become Be2+, it now has 2 electrons remaining, both in the inner shell.
An element with 2 energy levels and 2 electrons in the outer layer is beryllium (Be). Beryllium has an atomic number of 4, with 2 electrons in the first energy level and 2 electrons in the second energy level, making it a neutral atom.

The most important isotope of beryllium - 9Be - has 5 neutrons. The neutral atom of beryllium has 4 electrons.
A neutral atom of Beryllium has 4 electrons. (Its atomic number is 4)
A neutral neon atom has 8 electrons in its outer shell. Neon has a total of 10 electrons, with 2 in the inner shell and 8 in the outer shell.
Beryllium has 2 outer shell electrons. Its full electronic configuration is:- 1s2, 2s2
There are 2 electrons in the outer orbit of a neutral atom of magnesium. This corresponds to the electron configuration of magnesium, which is [Ne] 3sĀ².
In an electrically neutral atom, the number of electrons is the same as the number of protons. Since the number of protons is the atomic number of an atom, and Beryllium has an atomic number of 4, this means that Beryllium has 4 protons in its nucleus. As mentioned previously, if the atom is electrically neutral, then Beryllium will also has 4 electrons.
The overall charge of a beryllium atom is neutral, meaning it has the same number of protons (+) in the nucleus as it does electrons (-) surrounding the nucleus. Beryllium has 4 protons and typically 4 electrons, resulting in a neutral charge.
