1st Semester final review #3: Periodic Table/Trends

Front

What is electronegativity?

Back

Electronegativity is a measure of the ability of an atom in a chemical compound to attract electrons from another atom in the compound.

Front

Which element has a stable octet in its ground state?

Back

Neon (Ne) has a stable octet in its ground state.

Front

Which element has chemical properties most similar to bromine?

Back

Fluorine (F) has chemical properties most similar to bromine.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in the gas phase.

Front

Which element has the greatest ionization energy: Ga, K, Bi, or As?

Back

Arsenic (As) has the greatest ionization energy among these elements.

Front

What do neutral atoms contain equal numbers of?

Back

Neutral atoms contain equal numbers of protons and electrons.

Front

What is the periodic trend for electronegativity?

Back

Electronegativity increases across a period from left to right and decreases down a group.

Front

What is the significance of a stable octet?

Back

A stable octet refers to an atom having eight electrons in its outer shell, leading to greater stability and lower reactivity.

Front

How do you determine the similarity of chemical properties among elements?

Back

Elements in the same group of the periodic table typically have similar chemical properties due to their similar valence electron configurations.

Front

What is the relationship between ionization energy and atomic size?

Back

Ionization energy generally increases as atomic size decreases because the electrons are held more tightly by the nucleus.
