11 what is an octet? a valence electrons 8 electrons 8 people singing 3. what is the electron - configuration equation for the element zn? 1s2, 2s2, 2p6, 3s2, 3p6, 3d6, 4s2 1s2, 2s4, 2p6, 3s2, 3p6, 3d10, 4s2 1s2, 2s2, 2p6, 3s2, 3p6, 4s2 3d10 18. what element does this orbital diagram represent? be b br

Explanation:

1. An octet refers to 8 electrons in the out - most shell of an atom which gives it a stable electron configuration.
2. Zinc (Zn) has an atomic number of 30. The electron - filling order is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰.
3. For the orbital diagram, if we assume it represents the filling of the first few orbitals, beryllium (Be) has 4 electrons with the electron configuration 1s²2s². Boron (B) has 5 electrons with configuration 1s²2s²2p¹ and bromine (Br) has many more electrons.

Answer:

1. 8 electrons
2. 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰
3. Be
