An atom can be an ion, but not all ions are atoms. The difference between an atom and an ion has to do with net electrical charge. ... The identity of an element is determined by the number of positively charged protons in the atom's nucleus. A stable atom contains the same number of electrons as protons and no net charge.
I hope it helps, I tried to keep it as concise as possible.
97 Electrons are in Britannium
<h2>Monosaccharides</h2>
Explanation:
Monosaccharides are the simplest form of sugars found in innumerable common food items such as honey, cane sugar, fruits
Monosaccharides are divided into two groups depending on the presence of functional groups,if aldehyde group is present then it is known aldoses and if ketone group is present then it is known as ketoses
On the basis of carbon atoms they can be classified as: triose(3),tetrose(4),pentose(5),hexose(6) and so on
a. erythrose : tetrose ketose-It is not correctly paired because erythrose is a tetrose monosaccharide which has one aldehyde group hence is an aldose
b. dihydroxyacetone : triose ketose-It is correctly paired;it is an aldose-ketose pair
c. erythrulose : tetrose aldose-It is not correctly paired because erythrulose is a tetrose monosaccharide having ketone as functional group hence is a ketose
d. fructose : hexose ketose-it is correctly paired;It is an anomer because in D-fructose carbonyl group is at C-2 hence C-2 is the anomeric carbon
e. ribose : hexose aldose-it is not correctly paired because ribose is an aldo pentose not hexose;ribose is an aldo-ketose pair
f. glyceraldehyde : triose aldose-it is correctly paired;an aldo group
