According to the octet rule, if an atom has fewer than 8 electrons in the outer most energy level, what is likely to happen?

1 answer:

8 0

According to the octet rule, If an atom has fewer than 8 electrons in the outer most energy level, it will react with other nearby atoms to give, receive or share electrons until it has a full outer shell. Option D.

<h3>What is the octet rule?</h3>

The octet rule is a theory stated by Lewis (1917) and is used to explain how atoms are combined.

The theory explains how atoms from different elements tend to complete their outer energy layer with 8 electrons to reach a stable electronic configuration.

The ions of different chemical elements complete their last energy levels when combined with other atoms.

Atoms can either gain or share electrons with other atoms to compose the molecule,

High electronegativity elements gain electrons until they get to complete the octet.

Low electronegativity elements lose or share electrons to get to the octet.

In this way, the rule explains how atoms form bonds to create a molecule.

The rule is used to predict the behavior of several substances according to their electronic configuration.

Among the options, the correct one is option D. if an atom has fewer than 8 electrons in the outer most energy level, it will react with other nearby atoms to give, receive or share electrons until it has a full outer shell.

Which is the correct sequence of the transfer of information in most organisms?

Phoenix [80]

The formation of DNA is a sequential process. First, the DNA molecule is transcribed on to an RNA molecule. This RNA molecule carries the information from the DNA from the nucleus to the cytoplasm, where it encounters ribosomes. The ribosomes then read the information on the RNA molecules and construct a chain of amino acids corresponding to the codons on the RNA molecule. The amino acids combine to form a protein.
Therefore, the correct sequence is C, DNA to RNA to protein.

Explain how the number of electrons in an energy level affects bond formation.

Klio2033 [76]

Hi,

The answer is very simple and of basic nature, let us get into the basics.

We have studied since very long that atoms form chemical bonds with other atoms because they want to get stable. They can get stable through octet or duplet rule that means that atoms needs to have two (in the shell nearest to nucleus) and eight electrons in the outer most shell.

So, if an atom already has enough number of electrons that it is obeying octet or duplet rule, it means that the atom is stable. It will tend not to form a chemical bond with other atom by sharing, losing or gaining electrons. Now, the electrons in outer most shell are called valence electrons and they are distributed in sub-energy levels, s and p respectively. S orbital can accommodate only two electrons, while P can accommodate 6 electrons, d can accommodate 10 electrons while f orbital can accommodate 14 electrons. So, we can say that the bond formation is the most important property of an atom and it is strongly effected by number of electrons in an energy level.

In addition, number of electrons in outer most shell also effect many other properties of an atom like shielding or screening effect, metallic or non-metallic nature that also effects the chemical bonding of atoms. Since, metallic nature of an atom is due to its ability to lose outermost shell's electrons. Therefore, the whole phenomenon of chemical bonding is linked with number of electrons in outer most shell.

Hope it helps!

Freshwater is defined as having a low _______ concentration, usually less than 1%.

vampirchik [111]

Answer: salt

Freshwater is defined as having a low salt concentration, usually less than 1%.

Explanation:

Freshwater refers to the bodies of water that contain very low levels of dissolved salts. So, freshwater are unique for their low salt content (about 0.5% of salt) compared to the sea water with high salt content.

Examples of freshwater include rivers and spring
