Homework Answers
A)
Covalent compound is formed by the two non-metal elements.
In sulfur hexafluoride, sulfur and fluorine both are non-metals hence, sulfur hexafluoride is a covalent compound.
B)
Air is the mixture of various gases, hence it does not have a definite formula.
Hence, Air has a definite formula is an incorrect statement.
C)
Element is made up of single type of atoms it means it is a pure substance made up of same kind of atoms.
Hence, it is a correct statement.
D)
Atom is the smallest particle of an element.
Hence, it is a correct statement.
Hence, statement B) Air has a definite formula is an incorrect statement.
