What is the modern periodic table?
The modern periodic table is a table that is arranged according to the increasing order of atomic numbers, where elements with similar chemical properties are placed in the same row and column.
What are the three main classes of elements in the periodic table?
The three main classes of elements in the periodic table are metals, nonmetals, and metalloids.
What is the number of periods and groups in the modern periodic table?
The modern periodic table has 7 periods and 18 groups.
What is the trend in atomic radius across a period in the periodic table?
Atomic radius decreases across a period in the periodic table due to increased nuclear charge and decreased shielding effect.
What is the trend in electronegativity down a group in the periodic table?
Electronegativity decreases down a group in the periodic table due to increased atomic size and increased shielding effect.
Which element has the highest electronegativity value in the periodic table?
Fluorine has the highest electronegativity value in the periodic table.
What is the trend in ionization energy down a group in the periodic table?
Ionization energy decreases down a group in the periodic table due to increased atomic size and increased shielding effect.
Which element has the highest ionization energy value in the periodic table?
Helium has the highest ionization energy value in the periodic table.
What is the trend in metallic character down a group in the periodic table?
Metallic character increases down a group in the periodic table due to increased atomic size and decreased ionization energy.
Which group of elements is known as the alkali metals?
Group 1 elements (excluding hydrogen) are known as the alkali metals.
Which group of elements is known as the halogens?
Group 17 elements are known as the halogens.
Which group of elements is known as the noble gases?
Group 18 elements are known as the noble gases.
What is the name given to the horizontal rows in the periodic table?
The horizontal rows in the periodic table are called periods.
What is the name given to the vertical columns in the periodic table?
The vertical columns in the periodic table are called groups.
