Answer:
Step-by-step explanation:
Atoms of sodium and chlorine are both elements, meaning they are made up of only one type of atom. Both have an atomic number of 11, which means they have 11 protons in their nucleus, but the number of neutrons and electrons differ. Sodium has 12 neutrons and 11 electrons, while chlorine has 17 neutrons and 17 electrons.
Atoms of sodium and chlorine are also both reactive, meaning they form chemical bonds with other elements. However, sodium is more reactive than chlorine, which is why it often forms compounds with other elements, such as sodium chloride (NaCl).
Atoms of sodium and chlorine are also similar in that they both have the same number of electrons in their outer shells. This means they can both form two covalent bonds with other elements. However, because the number of electrons and neutrons in each atom is different, the strength of the bonds they form will differ.
Overall, atoms of sodium and chlorine are similar in that they both have 11 protons and can form two covalent bonds, but they differ in their number of neutrons and electrons, which affects the strength of the bonds they form and their reactivity.
