Explain how ionic bonds form.
ionic bonds form when one atom gives away electrons to another atom, making both atoms charged (one negative and one positive). These opposite charges attract one another creating a strong bond that holds them together.
Explain why covalent bonds form between atoms?
Covalent bonds form when atoms share electrons so that each atom can feel like it has a full other shell of electrons. This sharing makes the atoms stick together in a strong bond.
Explain how metallic bonds form.
Metallic bonds form when metal atoms group together and share their outer elections freely, Instead of each election staying with one atom, the electrons move around all the atoms in a "sea of electrons." This "sea" holds the metal atoms together
An unknown substance is found to be brittle to touch but has a high melting point. What type of bond must it be?
Ionic Bond
What is Mr. Humble's favourite hobby?
Fishing
What is the name of the force that holds ionic bonds together?
Electrostatic Attraction
Why can covalent compounds not conduct electricity?
There are no charged particles present in the bond, therefore they cannot carry a charge.
Why are metals good conductors? (explain using the structure of a metallic bond).
Atoms are packed together closely and their elections can move around freely like a "sea" of electrons which helps them conduct.
An unknown substance is conductive in it's solid state at room temperature. What type of bond must it be?
Metallic Bond
What is the worlds largest desert?
Antarctica.
