FLASHCARD QUESTION

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It is a key factor in determining how atoms interact in chemical bonds.

2.

FLASHCARD QUESTION

Front

How does electronegativity change across a period in the periodic table?

Back

Electronegativity generally increases from left to right across a period due to increasing nuclear charge, which attracts electrons more strongly.

3.

FLASHCARD QUESTION

Front

How does electronegativity change down a group in the periodic table?

Back

Electronegativity generally decreases down a group because the increased distance between the nucleus and the valence electrons reduces the nucleus's ability to attract bonding electrons.

4.

FLASHCARD QUESTION

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state. It is an important property that influences an element's reactivity.

5.

FLASHCARD QUESTION

Front

How does ionization energy change across a period in the periodic table?

Back

Ionization energy generally increases from left to right across a period due to increasing nuclear charge and decreasing atomic radius.

6.

FLASHCARD QUESTION

Front

How does ionization energy change down a group in the periodic table?

Back

Ionization energy generally decreases down a group because the outer electrons are further from the nucleus and are shielded by inner electrons, making them easier to remove.

7.

FLASHCARD QUESTION

Front

What is the relationship between electronegativity and ionization energy?

Back

Elements with high electronegativity typically have high ionization energy, as both properties are influenced by the effective nuclear charge and the distance of valence electrons from the nucleus.
