Below is an attachment of the Lewis structure with the lowest formal charges.
The formal charge is the fictitious charge that an atom in a molecule would have if the electrons in the bonds were evenly distributed among the atoms. The nonbonding electrons on a neutral atom are subtracted from its valence electron count, which is then followed by the number of bonds that bind it to other atoms in the Lewis structure, to get the formal charge. This is another way to put it. When hyponitrous acid is oxidized in the atmosphere, nitric and nitrous acids are produced. By reducing a nitrate or nitrite by sodium amalgam in the presence of water, hyponitrite salts have been created.

Answer:
Phosphorus-28 undergoes beta-minus decay to produce
- an electron,
- a Silicon-28 nuclei, and
- an electron antineutrino.
Explanation:
In simple words, when a nucleus undergoes beta-minus decay, a neutron is converted to a proton. An electron and an electron antineutrino will be released.
.
One way to tell whether a neutron is converted to a proton, but not vice versa, is to check the sum charges on the two sides of this equation.
- Left-hand side: 0. Neutron is neutral.
- Right-hand side: 1 + (-1) = 0. Each proton carries a charge of +1. Each electron (beta-minus particle) carries a charge of -1. Antineutrinos are neutral.
The charges on the two sides of this equation is the same. Hence this nuclear equation is possible (but not necessarily correct; however, if the proton and the neutron are in the wrong place the charge won't even be the same.)
Since the mass number of a proton and a neutron are both 1, the overall mass number of the atom will stay the same.
The atomic number is the number of protons in each atom. That number determines the symbol and the chemical properties of the atom. When one neutron in an atom is converted to a proton, the atomic number of the atom will increase by 1.
The atomic number of the daughter nucleus, silicon, is 14. It takes a parent nucleus with atomic number to produce a silicon atom. Refer to a modern periodic table. Atomic number
corresponds to the element aluminum.
Also, the mass number of the daughter nucleus is 28. Since the mass number would stay the same in a beta decay, the mass number of the parent nucleus would also be 28. In other words, it takes an aluminum-28 atom to undergo beta-decay to produce a silicon-28 atom.
