Answer:
Explanation:
A is Magnesium, B is Aluminium both are adjacent element and lie in third period.
Magnesium with atomic number of 12 consist two s electrons in it's valence shell in ground state whereas, Aluminium which has atomic number of 13 consist three electrons in it's valence shell in the ground state out of which two are s electrons and only one p electron.
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
Answer:
Isomers are defined as the molecules or polyatomic ions which have similar molecular formula but different in arrangements of atoms.
Isomers can be found in food items carrying glucose (C6H12O6), galactose or fructose, they all have the same chemical formula but differ structurally and chemically.
Glucose is found in vegetables and milk, galactose found in dairy products, and Fructose is found in fruit juices.
