True
Explanation:
Because the sun is a star, all stars eventually explode after a certain amount of time
The atomic number is the number of protons, while the atomic mass is the number of protons added to the number of neutrons. By definition, potassium (K) has atomic number 19, so it should have 19 protons. If it has a mass of 42, then the number of neutrons is 42 - 19 = 23 neutrons. This is choice (1).
Inorganic molecules are composed of other elements. They can contain hydrogen or carbon, but if they have both, they are organic.
A bond is a force of attraction between atoms as a result of transfer or sharing of electrons. Covalent bond is a bond between non metal atoms that results from sharing of electrons between the atoms. A single atom is formed when atoms share a pair of electron during formation of covalent bonds. Therefore, single covalent bonds exist in a molecule of carbon tetrachloride ( 4 single covalent bonds )
