Answer and Explanation:
Ions are electrically charged particles that are formed from the removing and addition of electrons. It can be a positively or negatively charged atom.
Answer:
Cl^-<NO3^-<H2O<F^-<CN^-
Explanation:
When we talk about base strength we are referring to how easily a chemical specie accepts protons.
The greater the ability of a specie to accept H^+, the greater its base strength.
The order of increasing base strengths of the species listed are shown in the answer above.
mass defect = mass of constituents - mass of atom
N has 7p and 9n
proton mass ~ 1.00728 amu
neutron mass ~ 1.00866 amu
electron mass ~ 0.000549 amu
Nitrogen mass ~ 14.003074 amu
mass defect = (7*1.00728)-(7*1.00866)-(7*0.000549)
- 14.003074
= 0.11235amu
convert to energy, the binding energy = 1.68x10^-11 J
