Answer:
Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together
Explanation:
Answer:
Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together. An ion is a positively or negatively charged particle .
Answer:An atom or a molecule can lose or gain electron(s) to form an ion. At this level students only need to know that an ion is a positively or negatively charged particle. However it may be worth introducing students to the electron at this point. When an atom/molecule gains negatively charged electron(s), a negative ion is formed. When an atom/molecule loses negatively charged electron(s), a positive ion is formed. This latter point is something students often struggle with later on in their studies. Introducing the electron now, before students meet the other sub-atomic particles, can help to embed the idea that the loss of electrons results in a positively charged ion, and may help reduce confusion later on.
Owing to the interweaving of the terms atom, ion and molecule when describing the different particles, it is unsurprising that students get confused. Using games and an element of competition can be helpful to bring some variety to the necessary student practice. One such game is based on the classic Connect 4 game.
