The first energy level is the 1s orbital, which can hold two electrons. Hydrogen is the first element, with just one electron, you write this down as 1s1. Helium is the second element, with two electrons, you write this down as 1s2. The second energy level has an s orbital and three p orbitals, holding two electrons each, making a total of eight. This element would be neon, you would write its electron configuration as 1s22s22p6. S orbitals are spherical; p orbitals are figure of eight shaped, with three arranged at right angles to one another. Each takes two 'spin-paired' electrons - one 'spinning up' and the other 'spinning down'. [apologies to previous contributor; I accidentally deleted your answer ]

How many electrons will carbon have in its first energy level?
carbon has 2 electrons in its first energy level and 4 in its secound energy level because carbons atomic number is 6. 4+2=6.
How many electrons on the fifth orbit?
The formula to determine the number of electrons in an energy level is 2n2, where n is the number of the energy level. For the fifth energy level, n=5. So the total number of electrons possible in the fifth energy level is 2(52) = 50.
Does an atom of helium have eight electrons in its outer energy level?
the largest number of electrons an atom of helium can have is 2, because it is in the first period, which means it can only have one energy level, which has a maximum capacity of two electrons
Which electrons in oxygen have more energy those in the first level or those in the second?
More energy have the electrons in the second level of energy.
How many electrons are required to fill the first shell?
The number of electrons in a shell is 2n2, where n=shell number. So for the first shell, there is a maximum of 2 electrons.
What is the number of electrons in the 1st energy level of magnesium?
All elements except hydrogen have two electrons in the first energy level.
What is the maximum number of electrons that can fit in an atom's first energy level?
2 electrons
How many electrons can be housed in the first energy level?
Two electrons can be housed in the first energy level.
How many electrons will carbon have in its first energy level?
carbon has 2 electrons in its first energy level and 4 in its secound energy level because carbons atomic number is 6. 4+2=6.
How many electrons does phosphorus have in its outermost principal energy level?
The total number of electrons in Phosphorus (P) is 15 (its atomic number). The first energy level contains 2, the second energy level contains 8, and the third energy level contains 5.
If the first and second energy levels of an atom are full.what would be the total number of electrons in the atom?
First energy level can hold 2 electrons.Second energy level can hold 2 + 6 = 8 electrons. Total = 10 electrons.
What the maximum number of electron can go in the first three energy levels subatomic particles?
the first energy levels hold 2, 8, and 18 a total of 28 electrons
Do noble gasses have the maximum number of electrons in their outer energy level?
yes.they have the maximum number of electrons in their outer energy level?
How many electrons on the fifth orbit?
The formula to determine the number of electrons in an energy level is 2n2, where n is the number of the energy level. For the fifth energy level, n=5. So the total number of electrons possible in the fifth energy level is 2(52) = 50.
The largest number of electrons found in the first energy level?
Two (in the case of helium).
How many electrons does calcium have and where are they located at?
The atomic number of calcium is 20 as it has 20 protons and 20 electrons, they are located outside the Nucleus in the orbits known as energy levels, and are commonly known as shells of the atom. in the first energy level there are 2 electrons, in the second energy level there are 8 electron, in the third energy level there are 8 electrons, and in the fourth energy level there are 2 electrons.
How many electrons are in the very first energy level?
there are two electrons in the first energy level of every element except for hydrogen which only has one electron in the first energy level.
