Periodic Table Flashcards
What is a group in the periodic table?
A group is a vertical column of elements in the periodic table that share similar chemical properties.
What is a period in the periodic table?
A period is a horizontal row of elements in the periodic table.
How many groups are there in the periodic table?
There are 18 groups in the periodic table.
How many periods are there in the periodic table?
There are 7 periods in the periodic table.
True or False: Elements in the same group have the same number of valence electrons.
True.
What is the main characteristic of alkali metals found in Group 1?
Alkali metals are highly reactive and have one valence electron.
Which group contains the noble gases?
Group 0 contains the noble gases.
Fill in the blank: The elements in Group 1 are known as __________.
alkaline metals.
What is the general trend of atomic size as you move down a group?
Atomic size increases as you move down a group.
What happens to the reactivity of nonmetals as you move from left to right across a period?
The reactivity of nonmetals increases from left to right across a period.
Which group is known for having elements that are very reactive and form salts?
Group 17, known as the halogens.
True or False: Transition metals are found in the d-block of the periodic table.
True.
What is the trend for ionization energy as you move across a period?
Ionization energy generally increases as you move from left to right across a period.
Short Answer: What do elements in the same period have in common?
Elements in the same period have the same number of electron shells.
What is the primary characteristic of elements in Group 1?
Low melting points, soft metals

f-block.
Which group contains the most reactive metals?
Group 1 contains the most reactive metals, known as alkali metals.
True or False: All noble gases are colorless and odorless.
True.
What is the trend in electronegativity as you move across a period?
Electronegativity generally increases as you move from left to right across a period.
What is the significance of the zigzag line in the periodic table?
The zigzag line separates metals from nonmetals.
