Diagram of Y10 Periodic Table VMA | Quizlet

It is a table in which elements are arranged into a series of rows and columns that obey specific patterns.

The original design of the elements is credited to Dmitri Mendeleev in the 1800s.

Periodic table of elements

An illustration of the different states of matter like solids, liquids and gases.

particle diagram

A molecule composed of one kind of atom; cannot be broken into simpler units by chemical reactions.

Elements

Groups of two or more atoms held together by chemical bonds

Molecules

A compound is a molecule that contains at least two different elements. All compounds are molecules but not all molecules are compounds.

compounds

The property that describes how readily a substance combines chemically with other substances

Reactivity

The horizontal rows on the periodic table.

Elements in the same row have the same number of electron shells/energy levels.

Period

The vertical columns on the periodic table.

Elements in the same group/family have the same number of valence electrons. (Except Helium which is in Group 8, but only has 2 valence e-)

Group

Number of protons and neutrons

Atomic mass

The number of protons in the nucleus of an atom

Atomic number

positively charged particles in the nucleus of an atom

protons

the particles of the nucleus that have no charge

neutrons

negatively charged particles found outside the nucleus

electrons

regions around the nucleus in which given electron or electron pair is likely to be found

orbitals

TERM

A fundamental grouping of elements such as sodium, gold, copper, and iron in the periodic table that have similar chemical and physical properties, (like Malleable,Ductile, Metallic luster, Solid at room temperature, are good conductors of electric current and heat.)

DEFINITION

Metals

Capable of being shaped.

Easy to shape or bend.

Malleable

Describes a material that can be pulled out into a long wire.

Ductile

TERM

The elements in Group 1A of the periodic table (except Hydrogen).

VIOLENTLY REACT with water, and produce alkaline (basic) substance.

DEFINITION

Alkali Metals
