Which scenario would cause a covalent bond to form?
nekit [7.7K]

Answer: A) Two atoms share electrons so they can fill their outer shells

Explanation: A covalent bond is a type of bond formed by sharing equal number of electrons between two non-metal atoms so that both of them can attain a stable octet or duplet structure of noble gases.

In covalent bonding, there is no loss or gain of electrons between atoms. For example, the formation of chlorine molecule, chlorine atom has seven electrons in its outermost shell, remaining one electron to attain an octet structure of noble gases. Two chlorine atoms share one pair of electron, each chlorine atom donating one electron to form a pair so that each atom in the chlorine molecule attains an octet structure..

The stage is the last stage of speciation The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.

Speciation is split into 3 stages:

a) Separation.

b) Adaptation.

c) Reproductive Isolation.

Stage 1 Separation

  • A part of the populace separates and adapts to a brand new environment. Natural occasions along with tsunamis, tidal waves can reason organisms to split from their preliminary habitat to a brand new environment.

Stage 2: Adaptation.

  • At this stage, the organisms evolve new trends that permit them to a brand new environment. They own sure traits that permit them to match into the brand new environment. Example The notable white skin's color makes it tough for it to be visible withinside the dark.

Stage 3: Reproductive Isolation.

  • At this stage, organisms of the equal species reunite and do now no longer interbreed. e, species are remoted into new ones in order that they have the great diversifications for or her new habitat.

<h3>What is speciation?</h3>

Speciation is an evolutionary method where the new species arises from previous ones.

Hence concluded that speciation involves the stage where the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
