Chapter2: Material & Structure Bonding

1. types of crystal

1.1. simple cubic (SC)

1.2. body centered cubic (FCC)

1.3. face centered cubic (FCC)

1.4. hexagonal close-packed (HCP)

2. the periodic table

2.1. the electron configuration of atoms. chemical reactivity, outer shell or valance electrons.

2.2. elements are arranged into rows (known as groups (+) or periods (-)

3. properties of mixture

3.1. composition of a mixture is variable

3.2. each of its component retain its characteristics

3.3. if component are easily. EXP: soil, ocean water, air.

4. atomic bonding

4.1. primary bonding

4.1.1. the nature of the bonding between their atomic or molecular components

4.1.1.1. covalent bonding

4.1.1.2. ionic bonding

4.1.1.3. metallic bonding

4.2. secondary bonding

4.2.1. physical bonds relatively weaker bonds between nearby atoms and molecules

4.2.1.1. dipole

4.2.1.2. hydrogen

5. properties of compound

5.1. components of a compound do not retain their individual properties. both sodium and chlorine are poisonous their compounds, table salt-NaCl is absolutely.

6. the periodic table

6.1. the electron configuration of atoms. chemical reactivity, outer shell or valence electrons.

7. atomic structure

7.1. has a concentrated nucleus containing the protons and neutrons surrounded by a cloud representing where the electron are likely to be found

7.1.1. PROTONS - in the nucleus (+ve)

7.1.2. NEUTRONS - in the nucleus (are natural, have no charge)

7.1.3. ELECTRONS - move in energy level outside of the nucleus (-ve)

8.1. atom

8.1.1. the basic unit of an element for all whether for solid, gas, liquid.

8.2. element

8.2.1. combination of two or more of one liquid of one of atom bending together.

8.3. mixture

8.3.1. various kinds of atoms combined together but not chemically.

8.4. compound

8.4.1. various kind of atoms, are combined together chemically with proportion.
