The periodic table is a tabular arrangement of chemical elements, organized based on their atomic number, electron configuration, and recurring chemical properties.
What are the periods in the periodic table?
Periods are rows in the periodic table that represent the number of electron shells an atom of an element has.
What are the groups (families) in the periodic table?
Groups are columns in the periodic table that represent elements with similar chemical properties and valence electron configurations.
What is atomic radius?
Atomic radius refers to the size of an atom, which can be determined by measuring the distance between the nucleus and the outermost electron orbital.
What is electronegativity?
Electronegativity is the tendency of an atom to attract electrons towards itself in a chemical bond.
How does atomic radius change across a period?
Atomic radius generally decreases from left to right across a period on the periodic table.
How does atomic radius change down a group?
Atomic radius generally increases from top to bottom within a group on the periodic table.
What is ionization energy?
Ionization energy is the energy required to remove an electron from a neutral atom, forming a positive ion.
How does ionization energy change across a period?
Ionization energy generally increases from left to right across a period on the periodic table.
How does ionization energy change down a group?
Ionization energy generally decreases from top to bottom within a group on the periodic table.

How does electronegativity change down a group?
Electronegativity generally decreases from top to bottom within a group on the periodic table.
What is the trend in metallic character?
Metallic character generally increases from right to left across a period and from top to bottom within a group on the periodic table.
What is the trend in reactivity?
Reactivity generally increases from left to right across a period and from top to bottom within a group on the periodic table.
What is the trend in valence electrons?
The number of valence electrons generally increases from left to right across a period and remains constant within a group on the periodic table.
