When atoms bond together to form molecules, they share or give electrons. If the electrons are shared equally by the atoms, then there is no resulting charge and the molecule is nonpolar.

Answer:
francium, caesium, helium
Answer:
The specific heat (\(c_s\)) of a substance is the amount of energy needed to raise the temperature of 1 g of the substance by 1°C, and the molar heat capacity (\(c_p\)) is the amount of energy needed to raise the temperature of 1 mol of a substance by 1°C. Liquid water has one of the highest specific heats known.
Explanation:
Answer: 207.24
Explanation: Atomic mass = no of protons + no of neutrons
1) 82 protons, 122 neutrons , mass number= 82+122 = 204
2) 82 protons, 125 neutrons, mass number= 82+125 = 207
3) 82 protons, 124 neutrons, mass number= 82+124 = 206
4) 82 protons, 126 neutrons, mass number= 82+126 = 208
Average atomic mass of an element = 
Average atomic mass of given element = 
The approximate atomic mass of lead is 207.24.
