How many atoms can the 2nd energy level hold?
8 electrons
The second energy level of atoms can hold a maximum of 8 electrons. The maximum number of electrons that an energy level can hold is determined from the formula 2n^2 equals the total number, where n is the energy level. Most elements that are essential in chemistry require eight electrons in each shell to be stable.
How many electrons can be in the 2nd energy level?
Explain that the second energy level can only have 8 electrons so the next electron in sodium has to be on the next (third) level.
How many energy levels are in the 2nd energy level?
two energy sublevels
There are two energy sublevels in the second principal energy level. The principal quantum number equals the number of sublevels within that principal energy level.
Which principal energy level can hold a maximum of 18 electrons?
The third principal energy level
The third principal energy level has one s orbital, three p orbitals, and five d orbitals, which can each hold up to 10 electrons. This allows for a maximum of 18 electrons.
How many energy levels do the elements in the 2nd row fill up?
Energy Levels The eight elements of the second row are filling their second energy level. It is the outermost electrons that determine the chemical properties of the element.
What is the highest energy level of an atom?
a. What is it meant by the highest occupied energy level in an atom? The highest occupied energy level in an atom is the electron-containing main energy level with the highest number.
How many electrons can the 2nd shell hold?
The second shell holds 8 electrons; 2 in a 2s orbital and 6 in three 2p orbitals. The third shell holds 18 electrons; 2 in a 3s orbital; 6 in three 3p orbitals; and 10 in five 3d orbitals.
How much energy is in an atom?
Secondly, how much energy is needed to produce one atom? Einstein showed that the energy associated with mass (m) is equal to m*c2, where c is the speed of light. The energy equivalent of a hydrogen atom is 0.16*10-9 joules or 0.16 billionths of a joule.
Does the third energy level hold 8 or 18 electrons?
1 Answer. The third shell in its lowest state has room for 8 electrons but including the higher energy 3d electrons it has a capacity of 18 electrons.
