Trends of the Periodic Table

Front

What is the trend of electronegativity in the periodic table?

Back

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

Front

Why does iodine have a smaller electronegativity value than fluorine?

Back

Iodine has a larger radius so it does not attract electrons easily.

Front

What do metals tend to do with electrons?

Back

Metals want to lose electrons and are therefore left with a positive charge.

Front

Why does potassium (K) have a larger atomic radius than sodium (Na)?

Back

K has more electron shells.

Front

Which family of non-metals is the most reactive?

Back

Halogens are the most reactive family of non-metals.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons.

Front

What is the trend of atomic radius in the periodic table?

Back

Atomic radius decreases across a period and increases down a group.

Front

What is ionization energy?

Back

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

Front

How does the atomic radius change as you move down a group in the periodic table?

Back

The atomic radius increases as you move down a group due to the addition of electron shells.

Front

What are noble gases known for in terms of reactivity?

Back

Noble gases are known for being largely unreactive due to their full valence electron shells.
