<span>Carbon can also bond with other
four atoms because of its outer shell (valence shell) that has four electrons.
This is the reason why organic molecules can be so large because of this
bonding. Suppose you have a compound of CCl4. You know that chlorine can only
share 1 electron because 7 of its electrons are filled. Also, in carbon, it can
only share 4 electrons because 4 of it are already filled. That is why carbon
needs four chlorine to form CCl4. The answer is letter <u>B.</u></span>
Bonding MO's have lower energy than antibonding MO's. The bonding MO's lower energy, even lower than its constituent atomic orbitals, accounts for the stability of a molecule in relation to its individual atoms. However, the sum of energy of the MO's must equal the sum of energy of the AO's.
<h3>What is atomic orbital?</h3>
An atomic orbital is a function in atomic theory and quantum mechanics that describes the location and wave-like behavior of an electron in an atom. This formula can be used to calculate the likelihood of locating any atom's electron in any given location surrounding the nucleus. The phrase atomic orbital can also refer to the actual region or place where the electron is projected to be present given the orbital's mathematical form.
Each orbital in an atom is defined by a set of values of the three quantum numbers n, l, and ml, which correspond to the energy, angular momentum, and an angular momentum vector component of the electron, respectively (magnetic quantum number).

Usually when metals and Nonmetals join they are held together by ionic bonds.
It is important in gravimetric analysis to add an excess amount of precipitating ions to a solution containing an analyte because it helps to determine the mass of the analyte.
<h3>What is Gravimetric analysis?</h3>
This is a method which is used in the determination of the quantitative determination of the ion being analyzed(analyte) based on its mass.
Adding an excess amount of precipitating ions to a solution containing an analyte will make it easier for the mass of an analyte to be determined.
It is also important for the precipitate to be a pure substance with a definite and known composition which therefore makes it the most appropriate reason.
