Escribe la configuración electrónica de los elementos que poseen, ¿de qué elementos se trata?: 15 electrones 27 electrones 56 el
allsm [11]

Answer:

15 electrones: 1S²2S²2P⁶3S²3P³. Fósforo

27 electrones: 1S²2S²2P⁶3S²3P⁶4S²3d⁷ - Cobalto.

56 electrones: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s² - Bario

49 electrones: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p¹ - Indio

Explanation:

Para llenar los orbitales electrónicos de los distintos átomos debemos hacer uso de la regla de llenado electrónico de Aufbau. Por ejemplo, para el átomo con 15 electrones, la configuración electrónica es:

1S²2S²2P⁶3S²3P³. 2+2+6+2+3 = 15 electrones

Si elemento es neutro, tiene 15 protones. Es decir, es el fósforo, P.

27 electrones:

1S²2S²2P⁶3S²3P⁶4S²3d⁷ - Cobalto.

56 electrones:

1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s² - Bario

49 electrones:

1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p¹ - Indio
