Answer 2

Answer:

1) Yes the statement is true. Explanation: Every satellite performing a circular motion needs a specific velocity called called a orbiting velocity.

2) Metallic character goes on decreasing while going from left to right in a period because the tendency of atoms of the elements to lose electrons (or gain electrons) changes in a period. As we move from left to right in a period, the nuclear charge increases due to a gradual increase in the number of protons.
