Isotopes, chemical bonding, properties of ionic compounds, and giant covalent bonds.

What are isotopes?

Isotopes are different versions of the same atom that contain the same number or protons but a different number of neutrons

Ionic bonding:

Formed when electrons are transferred between 2 or more atoms

Covalent bonding

Formed when electrons are shared between 2 or more atoms

What is an anion?

It is a negatively charged ion

what is a cation?

It is a positively charged ion

What is a molecule?

It is a substance that contains covalent bonds

What is a mixture?

It is when 2 or more elements are mixed together without being chemically bonded

What is an element?

It is a substance that cannot be chemically broken down any further

What is the first property of ionic compounds?

Ionic compound can conduct electricity in its molten state or when dissolved in water because water is attached to charged ions.

What is the second property of ionic compounds?

Ionic compounds have a high melting and boiling point, due to the strength between the electrostatic forces, it is harder to break the bonds.

What is the third property of ionic compounds?

They are solid at room temperature because they are in a regular arrangement in a lattice structure, so ions with opposite charges ae next to each other.

State 4 differences between diamond and graphite:

1: Diamond is tightly packed while graphite is in a layered structure

2: Diamond can’t conduct electricity while graphite can

3: Diamond is hard while graphite is soft

4: Diamond is clear and transparent while graphite is opaque

In what structure is diamond arranged in vs graphite?

Diamond is tightly packed in a tetrahedral structure while diamond is in a layered structure

How many carbon atoms are attached to each diamond atoms vs carbon?

Diamond: 4 carbon atoms

Graphite: 3 carbon atoms

Study ionic and covalent bonding and study how to write the chemical formula for any compound or molecule.
