The electronegativity values of three elements 'X', 'Y' and 'Z' are 0.93, 2.6 and 3.2, respectively. The chemical bond formed between the atoms of 'X' and 'Z' will be ___________ and the chemical bond formed between 'Y' and 'Z' will be __________.

The tendency of an atom to attract electrons towards itself when combined in a compound is called electronegativity. If the difference in electronegativity values between the combining atoms is more, then the chemical bond formed between them will be electrovalent. If the difference in electronegativity values between the combining atoms is less, then the chemical bond formed between them will be covalent.
