Periodic Table & Trends-MURRAY

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It increases across a period and decreases down a group in the periodic table.

Front

Which element has the highest electronegativity in the periodic table?

Back

Fluorine (F) has the highest electronegativity.

Front

How many valence electrons does Potassium (K) have?

Back

Potassium (K) has 1 valence electron.

Front

What is a group in the periodic table?

Back

A group is a vertical column in the periodic table where elements have similar chemical properties due to having the same number of valence electrons.

Front

What is an alkali metal?

Back

Alkali metals are the elements in Group 1 of the periodic table, characterized by having one valence electron and being highly reactive. Examples include Lithium (Li), Sodium (Na), and Potassium (K).

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state. It generally increases across a period and decreases down a group.

Front

Which element has a lower ionization energy than Scandium (Sc)?

Back

Calcium (Ca) has a lower ionization energy than Scandium (Sc).

Front

What is the trend of electronegativity in the periodic table?

Back

Electronegativity increases from left to right across a period and decreases from top to bottom within a group.

Front

What are the main categories of elements in the periodic table?

Back

The main categories are metals, nonmetals, and metalloids.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties, allowing for predictions about element behavior.
