thank you, that was helpful.
Astrokel's response is appropriate, this is the type of question designed as much to assess your literature (textbook) searching and comprehension skills as much as getting the answer right. If we "spoon feed" you an answer we are preventing you from acquiring the skills you need to progress in future.
Hit the books and put some effort in also, was the bit in bold typed correctly?
"why is HCL covalently
bonded? Why is CH4 covalently bonded?
How do you classify between a covalent bond and an ionic bond?
Please give some examples."
