lesya692 [45]

Answer:

1s2 2s2 2p4

Explicación:

1s2 2s2 2p4 es la configuración electrónica de la molécula de agua. En el agua, hay 10 electrones, dos de hidrógeno y ocho de oxígeno. La subcapa 2s contiene un máximo de 2 electrones, mientras que la capa 2p puede acomodar seis electrones. El átomo de hidrógeno pertenece al primer grupo y el átomo de oxígeno pertenece al sexto grupo de la tabla periódica. En la estructura de Lewis, un átomo de oxígeno está unido a dos átomos de hidrógeno en un ángulo de 104,45 grados. Existe un enlace covalente presente entre el hidrógeno y el átomo de oxígeno en el que ambos se vuelven estables. El oxígeno necesita dos electrones, por lo que forma enlaces con dos átomos de hidrógeno que tienen un electrón cada uno.
