Describe how elements form bonds?
Investigate how valence electrons related to chemical bonds?
Differentiate between ionic and covalent bonding?
THANK YOU:3
Answer:
1. Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. ... A covalent bond involves a pair of electrons being shared between atoms. Atoms form covalent bonds in order to reach a more stable state.
2. The electrons in any given element's outer shell are its valence electrons. When elements share electrons, a strong covalent bond is formed. ... When an element gives away an outer electron, it results in oppositely charged ions that are held together by a weaker ionic bond.
3.Ionic bonds result from transfer of electrons, whereas covalent bonds are formed by sharing. 2. Ionic bonds are electrostatic in nature, resulting from that attraction of positive and negative ions that result from the electron transfer process; charge separation between covalently bonded atoms is less extreme.

If your eye was punctured by a large needle, what gel-like material would come out?
Select one:
a. iris
b. cornea
C. Sclera
d. vitreous humor
The gel-like material that should come out is Vitreous humor.
The information regarding the vitreous humor is as follows:
It is the gel-like substance that should be located at the eye chamber. By this, it helps to maintain the eye rounded shape also the vision should be cleared.Moreover, it fills the eyeballs that are behind the lens.Therefore we can conclude that the gel-like material that should come out is Vitreous humor.
