Answer:
We know the information about atomic size, energy, electronic configuration etc. of atom from the periodic table.
Explanation:
- Periodic table is the arrangement of elements that are arranged according to their properties and electronic configuration.
- In periodic table, on furthest right side of the periodic table, noble gases like He, Ne, Ar etc are arranged.
- The atomic number of element increases while moving from left towards right in the periodic table.
- The metallic character of element decreases as we proceed the table towards right.
- They readily accept electron to fill the valence shell hence becoming more metallic in character.

Answer:
In the order largest to smallest
Pc = Pb, Pa
Explanation:
Power = Energy expended/time
Pa = 2/2 = 1Watt
Pb = 10/5 = 2Watt
Pc = 2E-3/1E-3 = 2Watt
Answer: 10m/s
Explanation: Since a single vector with length of 1cm expresses 5m/s, the vector which has a length doubled from the original vector should have the speed which is also doubled.
