This element is likely phosphorus (P), which has 15 electrons in total. With 5 electrons in the second energy level, phosphorus has 2 energy levels: the first energy level with 2 electrons and the second energy level with 5 electrons.
The element with 2 electrons in the second ring is helium. Helium has 2 electrons in its second energy level.
The first element with an electron in the second energy level is lithium. Lithium has three electrons, with two in the first energy level and one in the second energy level.
Carbon. Carbon is in the second period, so it has electrons in its second energy level, and it is in the fourth group in the second energy level, so it has 4 electrons.
The element sulfur (S) has 16 electrons. It has 2 electrons in its first energy level, 8 electrons in its second energy level, and 6 electrons in its third energy level.
The element you are referring to is beryllium (Be). Beryllium is an alkaline Earth metal that has two electrons in the second energy level.
An element with two energy levels can have a maximum of 8 electrons. The first energy level can hold up to 2 electrons, while the second energy level can hold up to 6 electrons.
The second energy level can hold a maximum of 8 electrons. Magnesium has 12 electrons, so in its second energy level, there will be 8 electrons (2 in the first energy level and 8 in the second energy level).
In the second energy level of an atom, there can be a maximum of 8 electrons. Magnesium has 12 electrons in total, with 2 electrons in the first energy level and 8 electrons in the second energy level.
Helium (He) has the electronic configuration 2.2 since it has 2 electrons in the first energy level and 2 electrons in the second energy level.
An atom with seven electrons will have five electrons in the second energy level.
A boron atom has three electrons in its second energy level.
