3 - sodium chloride (salt) - about 25 of the 92 natural elements are essential to life - carbon, hydrogen, oxygen, and nitrogen make up 96% of living matter - most of the remaining 4% consists of calcium, phosphorus, potassium, and sulfur - character elements are those postulate by an organism in exquisite quantities - Table 2.1 - necessity elements and trace elements in the charitable body - Fig. 2.4 - ace deficiency that has engage to a goitre (inflamed and self-conceited thyroidal gland) - each element consists of unique atoms - an atom is the smallest whole of matter that still retains the properties of an element - atoms are ecomposed of subatomic particles (protons - positive charge, neutrons - no charge, and electrons - minus charge) - neutrons and protons are in the...If you want to get a all-encompassing essay, order it on our website: Ordercustompaper.com
