Na+1 Electron Configuration

Question

what is Na+1 Electron Configuration, noble gas notation, orbital notation and E-dot

Answer 1

To get the electron configuration of Na⁺, we can first start with that for Na (ground state).

Na has 11 electrons: 1s² 2s² 2p⁶ 3s¹

Na+ has lost the outermost (3s¹) electron in order to gain a + charge: 1s² 2s² 2p⁶

Noble gas notation: [Ne]

Orbital notation: ↑↓ ↑↓ ↑↓ ↑↓ ↑↓

...........................1s...2s......2p.............

E-dot: difficult to draw on this platform but you'd have [ Na ]⁺ and put four lone pairs around the Na, i.e. put 2 dots on top, 2 on the bottom, 2 to the right and 2 to the left.
