You need to look at the electronegativity and decide wheter the difference of both of the numbers are significant enough to form a polar bond
Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object's atoms heat up. Light travels in waves and is the only form of energy visible to the human eye.
The reason why modelling is used in the study of earth science processes is further explained below
<h3>What is earth science?</h3>
Earth science is defined as the branch of science that deals with the geology, oceanology and meteorology aspects of life.
Because these fields covered by earth sciences is are often not visible, models are used for its study for better understanding.

<span>The atoms in a compound are held together by a chemical bond. The chemical bonds can be either covalent bonds or ionic bonds. Both the bonds are considered very strong bonds. These bonds are mainly formed by sharing of electrons or in the case when one of the elements making the compound donates electron to the other element. The nucleus of each atom attracts to form a strong bond. This property of attraction between the nucleus of the atoms actually helps in forming the chemical bonds. </span>
