Chemical bonding is a fundamental concept that explains how atoms combine to form compounds. There are several types of bonds, each with distinct properties and behaviors. Ionic bonds form when electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions. These ions are held together by electrostatic forces. Covalent bonds occur when atoms share pairs of electrons, leading to the formation of molecules. Metallic bonds, found in metals, involve a 'sea' of delocalized electrons surrounding positive metal ions. Each type of bond influences the physical properties of the substance. For example, ionic compounds typically have high melting and boiling points and conduct electricity when molten or dissolved in water. Covalent compounds can have varying physical states and usually do not conduct electricity. Metals are characterized by their malleability, ductility, and electrical conductivity. Which type of bond is responsible for the high melting and boiling points of ionic compounds? A. Covalent bond B. Ionic bond C. Metallic bond D. Hydrogen bond
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
