Answer:
B. Nuclear fission
Explanation:
Nuclear binding energy is used to determine whether fission or fusion will be a favorable process. The mass defect of a nucleus represents the mass of the energy binding the nucleus, and is the difference between the mass of a nucleus and the sum of the masses of the nucleons of which it is composed.
Answer: H
H- C- H
H
Explanation:
Lewis structures are the structures which represent the valence electrons of the element around the chemical symbol of the element.
Carbon is an element which belong to group 14. Atomic number of carbon is 6 that means it contains 6 electrons, Thus the electronic configuration is represented as:
. Thus the valence electrons are 4.
Hydrogen is an element which belong to group 1. Atomic number of hydrogen is 1 that means it contains 1 electron, Thus the electronic configuration is represented as:
. Thus the valence electron are 1.
The four valence electrons of carbon are shared with one valence electron of hydrogen each.
Answer:
Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons
