LAS 4: THE PERIODIC TABLE

Periodic Table

Is a chart that arranges all known chemical elements in order of increasing atomic number so that elements with similar properties are grouped together.

Periodic Table

It helps scientists quickly see patterns in element behavior, predict properties, and understand relationships between elements.

Nihonium (Nh), Moscovium (Mc), Tennessine (Ts), and Oganesson (Og)

What are the newly discovered elements?

Periods

These are the horizontal rows of the periodic table.

Seven

There are how many periods in the periodic table?

Periods

This represents the energy level an element occupy.

Groups

These are the vertical columns of the periodic table.

Groups

This characterizes the similarities of the physical and chemical properties of an element.

Families

What is another name for Groups in the periodic table?

S-block

This contains the Group IA and Group IIA elements.

P-block

This contains the Group IIIA to Group VIIIA elements.

D-block

This contains the transition metals.

F-block

This contains the inner transition metals (Lanthanides and Actinides Series).

Lanthanides and Actinides Series

What is the name of the series of the inner transition metals?

Metals

These are located at the left part of the periodic table.

Malleability

It is the ability to be pounded into thin sheets.

Melting Point

The temperature at which a solid changes into a liquid.

State of Matter

The physical form in which a substance exists: solid, liquid, gas, and plasma.

Luster

The way a surface reflects light; how shiny or dull a material appears.

Electrical Conductivity

The ability of a substance to allow electric current to pass through it.

Ductility

The ability of a material to be stretched or drawn into wires without breaking.

Atomic Size

The size of atomic specie as determine by the boundaries of the valence electrons.

Ionization Energy

The energy required to remove a valence electron from an atomic specie.

Electron Affinity

It is the amount of energy release when a neutral atom accepts an electron in its outermost shell to convert it to negatively charged ion.

Electronegativity

Tendency of an atom to attract a shared pair of electrons.
