Cual es el enlace covalente de H2 SE​
Veronika [31]
Su enlace es covalente apolar.
Explicación:
Ambas moléculas se unen para formar un compuesto estable, y alcanzar el "octeto".
El selenio tiene 6 electrones de valencia, y le faltaría dos electrones, para tener los 8 electrones, y así, cumplir su octeto, y volverse estable.
Por el contrario, el hidrógeno, se va a parecer al elemento noble más estable, el Helio (He), por lo cual, puede compartir sus electrones con el Selenio, así el Hidrógeno tendría 2 electrones, volviéndose estable, y el Selenio 8.
Sabiendo lo anterior, podemos calcular si es covalente polar o apolar, con una tabla de electronegatividad, que puedes encontrar en internet.
Restas el valor del Selenio al Hidrógeno, y el resultado que te de, lo comparas son los valores de referencia existentes, quedando como:
Se(2.6)-H(2.2)= 0.4
Covalente apolar: 0-0.4
Covalente polar: 0.5-1.6
