Bonds

What is a compound?

• A substance formed when two or more different elements are chemically bonded together.

• A mixture of two or more substances that retain their individual properties.

• A single element that cannot be broken down into simpler substances.

• A solution where one substance is dissolved in another.

What type of bond is water (H2O)?

• Ionic bond

• Covalent bond

• Metallic bond

• Hydrogen bond

What is metallic bonding known for?

• Having valence electrons moving like a sea to make the bond strong.

• Having fixed valence electrons that do not move.

• Forming strong covalent bonds between atoms.

• Creating a rigid structure with no electron movement.

What is the octet rule?

• Atoms tend to bond in such a way that they have eight electrons in their valence shell.

• Atoms prefer to have four electrons in their outer shell.

• Atoms will always have a full outer shell of two electrons.

• Atoms can bond in any configuration regardless of their electron count.

What type of bond is salt (NaCl)?

• Covalent bond

• Ionic bond

• Metallic bond

• Hydrogen bond

What is a cation?

• A negatively charged ion.

• A positively charged ion.

• An ion with no charge.

• A neutral atom.

What is a covalent bond?

• A bond formed by the sharing of electrons between atoms.

• A bond formed by the transfer of electrons from one atom to another.

• A bond that occurs between two metals only.

• A bond that involves the attraction between oppositely charged ions.

What is a metallic bond?

• A bond formed by the attraction between positively charged metal ions and the electrons in a 'sea' of electrons.

• A bond formed by the sharing of electrons between two non-metal atoms.

• A bond that occurs between two metal atoms through the transfer of electrons.

• A bond formed by the electrostatic attraction between oppositely charged ions.

What is a valence electron?

• An electron in the outermost energy level.

• An electron that is closest to the nucleus.

• An electron that is involved in nuclear reactions.

• An electron that has a negative charge.

What is electronegativity?

• A measure of the tendency of an atom to attract a bonding pair of electrons.

• The ability of an atom to lose electrons easily.

• The measure of an atom's size in a molecule.

• The energy required to remove an electron from an atom.
