Answer:
Most puppies are born head first but some come tail first. Puppies are born inside a thin sac, which the mother will remove, enabling them to breathe. After each puppy, your dog should pass an afterbirth (placenta), which they often eat.
Explanation:
The ionization energies (kJ/mol) of hydrogen, nitrogen, sodium, chlorine, and fluorine are 1,312, 1,402, 496, 1,256, and 1,681,

Answer: Sodium will most likely to become a monoatomic ion with fluorine when these atoms interact.
Explanation:
Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.
With increase in atomic size of the atom, there will be less force of attraction between the nucleus and the valence electrons of the atom. Hence, with lesser amount of energy the valence electrons can be removed.
More is the value of ionization energy more it is difficult to remove an electron. Therefore, lesser is the reactivity of element.
Hence, we can conclude that sodium will most likely to become a monoatomic ion with fluorine when these atoms interact.
