This example compares the Worksheet.Range property, Application.Union method, and Application.Intersect method.

Range("A1:A10").Select                            'Selects cells A1 to A10.
Range(Range("A1"), Range("A10")).Select           'Selects cells A1 to A10.
Range("A1, A10").Select                           'Selects cells A1 and A10.
Union(Range("A1"), Range("A10")).Select           'Selects cells A1 and A10.
Range("A1:A5 A5:A10").Select                      'Selects cell A5.
Intersect(Range("A1:A5"), Range("A5:A10")).Select 'Selects cell A5.
