Explanation
## Step1 The first statement refers to the interaction of atoms or molecules with each other. This interaction can be in the form of chemical reactions, where the atoms or molecules react with each other to form new substances.## Step2 The second statement is referring to the process of forming an ionic bond. This involves the transfer of electrons from one atom to another, leading to the formation of ions.## Step3 The third statement is about the composition of molecules. A molecule can be formed by two or more atoms of the same element, or of different elements. For example, a molecule of water (H2O) is formed by two hydrogen atoms and one oxygen atom.## Step4 The fourth statement is about the release of energy in a chemical reaction. This is known as an exothermic reaction, where energy is released to the surroundings.## Step5 The fifth statement is about the law of conservation of matter. This law states that matter cannot be created or destroyed in a chemical reaction.## Step6 The sixth statement is about the chemical formula, which is a way of expressing the numbers and types of atoms in a compound.## Step7 The seventh statement is about the products of a chemical reaction. These are the substances that are formed as a result of the reaction.## Step8 The eighth statement is about a balanced chemical equation. This is an equation where the same number of atoms of each element is found on both sides of the equation.## Step9 The ninth statement is about elements with the same number of valence electrons. These elements are found in the same group on the periodic table because they exhibit similar chemical properties.## Step10 The tenth statement is about the combination of two or more atoms. This combination forms a molecule.## Step11 The eleventh statement is about a substance that is formed as a result of a reaction. This is known as a product.## Step12 The twelfth statement is about the law of conservation of matter. This law states that matter cannot be created or destroyed in a chemical reaction.## Step13 The thirteenth statement is about the tendency of atoms to combine with other atoms. This is done to achieve a stable electron configuration, typically having eight electrons in the outer shell.
