2 electrons is the maximum number for an single orbital.
2
2 electrons maximum. 1s2
Iodine has 7 valence electrons. I- contains 8 valence electron.
we know that 1st shell contain 2 electrons 2nd shell 8 electrons but third shell have to contains 18 electrons but the maximum no. of electrons that can be accommodated in the outermost orbit is 8 electrons...... by yhell
The maximum number of electrons in the second principle energy level (n=2) is 8. This can be determined from 2(n^2) which for n=2 would be 2 x 4 = 8. It can also be seen by writing the electron configuration for n=2 which would be 2s2 2p6 for a total of 8 electrons.
Two (2) electrons can be held in the first orbit.
1st orbit - 2 2nd orbit - 8 3rd orbit - 8 all together all three orbits can hold up to 18 electrons.
8 for the 3rd orbit Actually there are 8 for the second. there are 18 for the third.
the max is 2 for the first orbitthe max is 8 for the second orbitthe max is 8 for the thrid orbit too.User:HeleneM5500:06, 4 Sep 2009 (UTC)Electrons follow paths called orbits, shells, or levels. Each shell can hold a specific maximum number of electrons. Each electron possesses a definite amount of energy. The radius of the orbit depends on the amount of energy that electron has & on the attractive force the nucleus has for that electron. Bohr model of the atom (with main energy levels identified by number: 1 --> 7Shell #1 closest to nucleus can hold a maximum of 2 each.Shell #2 next shell outward can hold a maximum of 8 each.Shell #3 next shell outward for elements Z = 1 --> 20, this shell can hold a maximum of 8 e-, for all others a maximum of 18 each.
95 electrons, two of them are in the outer orbit.
False!! ~KAILEN APRIL
A limited number of electrons...
According to the Bohr's atomic model the number of electrons present in a orbit can be defined by p(n.n) i.e p.n square,where n=number of orbit.hence we can calculate the number of electrons present in second orbit i.e 8.
