✿ANSWER✿
2) Covalent bonds form when electrons are shared between atoms and are attracted by the nuclei of both atoms. In pure covalent bonds, the electrons are shared equally. ... The ability of an atom to attract a pair of electrons in a chemical bond is called its electronegativity.
3) Molecules and polyatomic ions are formed by covalent bonds. Molecules are neutral particles formed by the sharing of electrons between multiple atoms.
4) Ionic bonds are electrostatic in nature, resulting from that attraction of positive and negative ions that result from the electron transfer process; charge separation between covalently bonded atoms is less extreme.
5) The chemical formula for carbon dioxide is CO2. Each carbon dioxide molecule contains one carbon atom and two oxygen atoms, bound to each other by covalent bonds. At room temperature and pressure, carbon dioxide is a gas.
5.a) molecule of the compound carbon dioxide contains one atom of the element carbon and two atoms of the element oxygen. Each oxygen atom shares a double bond with the carbon atom. Carbon is the sixth element in the periodic table and occurs in pure form as coal and diamonds. Oxygen, element eight, is a gas that makes up about 21 percent of the atmosphere. Living things take in oxygen and release carbon dioxide. The oxygen helps turn food into energy, creating carbon dioxide as a byproduct. Green plants use carbon dioxide in photosynthesis to make and store carbohydrates, the plants’ food source.
b) Sugar is made up of carbon, hydrogen and oxygen atoms. It's the way these atoms are connected that makes each type of carbohydrate different.
c) refer to the given attachment for the diagram
