In which of the following will hydrogen form ionic compound?
HCL
NaH
NH\(_3\)
CH\(_4\)
Explicació
NaH is a saline (salt-like) hydride, composed of Na+ and H− ions.
NaH (sodium hydride) is considered an ionic compound because it is composed of a metal (sodium) and a non-metal (hydrogen), where sodium readily loses an electron to form a positive ion (Na+) and hydrogen gains an electron to form a negative ion (H-) creating an ionic bond between them.
