State the definition of an ionic bond and a covalent bond and give examples of both.
An ionic bond occurs when one atom gives up one or more electrons to another atom. This type of bond occurs between a metal ion and a non-metal ion. Example of an ionic bond is NaI where Na- sodium being the alkali metal and I- iodine being the non-metal. A covalent bond occurs when atoms share electrons. This type of bond forms between two nonmetal ions. Example of a covalent bond is H2O, where H2- two hydrogen ions in nature are in the gas state (nonmetal) and O- oxygen is also a nonmetal.
What is the difference between photosynthesis and cellular respiration? Give an example of an organism that uses photosynthesis.
Photosynthesis is the process that uses energy from the sun or a light source to convert water and carbon dioxide into sugars. Cellular respiration is a set of metabolic process that converts biochemical energy into adenosine triphosphate also known as ATP and waste. Plants undergo photosynthesis with the help of their organelles, chloroplast.
