WebSep 20, 2024 · An atom is most stable if its outermost energy level contains as many electrons as it can hold. For example, helium has two electrons, both in the first energy level. This energy level can hold only two electrons, so helium’s only energy level is full. This makes helium a very stable element. WebThe electron configuration for lithium uses only the 1s and 2s subshells. The third electron in lithium has to go into the second level because the 1s is completely filled after two electrons occupy the level. You try doing the … list of isi architectural journals

WebApr 9, 2024 · Here the value of l is 1. So, (2l + 1) = 3. The p subshell has a maximum of 3 orbitals and each orbital contains a maximum of 2 electrons. So, a maximum of 6 electrons fit in the orbital for which n=3 and l = 1. Hence, the correct option is (D) 6. Note: The p sub-shell is a dumb-bell shape. The p subshell has 3 orbital. WebApr 24, 2024 · The number of elements in each row shows how many electrons it takes to fill each level. Hydrogen and helium are in the first row, or period, on the periodic table. Therefore, the first energy level can have … WebFeb 19, 2014 · The first shell can carry up to two electrons, the second shell can carry up to eight electrons.
