Answer 1

Răspuns:

₁H: 1(K) - 1e⁻ (1s¹)

₇N: 1(K) - 2e⁻, 2(L) - 5e⁻ (1s² 2s²2p³)

₈O: 1(K) - 2e⁻, 2(L) - 6e⁻ (1s² 2s²2p⁴)

₁₄Si: 1(K) - 2e⁻, 2(L) - 8e⁻, 3(M) - 4e⁻ (1s²2s²2p⁶ 3s²3p²)

₂₂Ti: 1(K) - 2e⁻, 2(L) - 8e⁻, 3(M) - 10e⁻, 4(N) - 2e⁻ (1s²2s²2p⁶3s²3p⁶3d²4s²)

₂₄Cr: 1(K) - 2e⁻, 2(L) - 8e⁻, 3(M) - 13e⁻, 4(N) - 1e⁻ (1s²2s²2p⁶3s²3p⁶3d⁵4s¹)

₂₉Cu: 1(K) - 2e⁻, 2(L) - 8e⁻, 3(M) - 18e⁻, 4(N) - 1e⁻ (1s²2s²2p⁶3s²3p⁶3d¹⁰4s¹)
