Answer: The correct option is D.
Explanation: Table salt has a chemical formula NaCl.
This compound is an ionic compound.
Ionic compound is defined as the compound formed when there is a complete transfer of electron from one element to another.
NaCl consists of two elements, Sodium (Na) and Chlorine (Cl)
Sodium has an atomic number of 11 and its electronic configuration is ![[Ne]3s^1](https://tex.z-dn.net/?f=%5BNe%5D3s%5E1)
. This element has 1 extra electron, so in order to have stable electronic configuration, this element will release 1 electron and forms a cation.
Chlorine has an atomic number of 17 and its electronic configuration is ![[Ne]3s^23p^5](https://tex.z-dn.net/?f=%5BNe%5D3s%5E23p%5E5)
. Chlorine element requires 1 electron to have stable electronic configuration. Hence, this element will accept 1 electron and will form an anion.
When these two element combine together, Sodium will give away 1 electron to chlorine and therefore, chlorine becomes anion.
Hence, the correct option is C.
I believe the correct answer from the choices listed above is option B. The best explanation for this happening would be that air <span>particles speed up and collide with the tire walls more often. As the particles are heated, kinetic energy increases. Hope this answers the question. Have a nice day.</span>
The principal quantum number (n): specifies the principal shell of the orbital.
The answer is option D.
The important quantum number (n) describes the dimensions of the orbital. Orbitals for which n = 2 are larger than those for which n = 1, as an example. Because they have got opposite electric costs, electrons are interested in the nucleus of the atom.
The numerals, called essential quantum numbers, imply strength degrees as well as the relative distance from the nucleus. A 1s electron occupies the energy stage nearest the nucleus.
A 2s electron, less strongly certain, spends most of its time farther far from the nucleus.
