Answer: In metallic bonding, valence electrons can move freely between atoms
Explanation:
when metals bond to one another, their outermost energy levels overlap. this allows valence electrons to move freely between atoms in what is sometimes called a “sea of electrons
(2) depletion of atmospheric oxygen
(3) exposure of workers to radiation
(4) exposure of workers to sulfur dioxide
Answer:
The correct answer is option 3, that is, exposure of workers to radiation.
Explanation:
The process of nuclear fission takes place when uranium nuclei get bombarded with neutrons. This association dissociates the uranium nuclei apart, discharging radiation, heat, and more neutrons. The neutrons, which gets discharged results in a chain reaction as more uranium nuclei get bombarded, generating huge amounts of energy.
The massive concern related to a nuclear power accident is the negative influences of radiation on the human body. If an individual gets exposed to an acute dose of greater levels of radiation, the outcome would be radiation sickness. Radiation sickness is illustrated as illness resulting due to exposure to a large dose of radiation over a brief time duration. The signs may comprise nausea, skin burns, diarrhea, vomiting, general weakness, hair loss, and possibly death.
The type of chemical bonding in sodium phosphate (Na3PO4) is ionic bonding. This is due to the transfer of electrons from sodium atoms to a phosphate group, forming ions which then attract one another to create a balanced, electrically neutral compound.
The chemical bonding in sodium phosphate (Na3PO4) is classified as ionic bonding. Ionic bonding involves the transfer of electrons from one atom to another, resulting in the formation of ions. This occurs between atoms of different electronegativities, typically a metal and a non-metal. Atoms lose or gain electrons to attain a stable, full outer electron shell.
In sodium phosphate, three sodium (Na) atoms each donate an electron to become positively charged ions (cations). The phosphate (PO4) group accepts these electrons to become a negatively charged ion (anion). The electrostatic attraction between the positive sodium ions and the negative phosphate ion forms the ionic bond. These discrete units assemble in a three-dimensional lattice structure in a way that ensures the overall compound is electrically neutral.
