Answer:
The compound GeH₄ is covalent.
Step-by-step explanation:
To know if a bond is ionic or covalent the rule says that when the electronegativity difference is greater than 2.0, the bond is considered ionic. If is less than 2.0, the bond is considered covalent.
The electronegativity of Germanium is 2.01 and electronegativity of Hydrogen is 2.2.
The electronegativity difference is:
2.2 - 2.01 = 0.19.
As the electronegativity difference is less than 2.0, the compound GeH₄ is covalent.
