Atomic Radius Trend

Front

What happens to the atomic radius as you move down a group in the periodic table?

Back

The atomic radius increases as you move down a group because more energy levels are added.

Front

Why do elements in the same group of the periodic table have similar chemical properties?

Back

Elements in the same group have the same number of valence electrons, which determines their chemical reactivity.

Front

What is the definition of atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is a cation?

Back

A cation is a positively charged ion.

Front

How does the atomic radius change as you move across a period from left to right?

Back

The atomic radius decreases as you move from left to right across a period due to increasing nuclear charge pulling electrons closer to the nucleus.

Front

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

Back

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

Front

What role do valence electrons play in determining the properties of elements?

Back

Valence electrons determine how an element reacts chemically and its bonding behavior.

Front

What is the relationship between atomic number and atomic radius?

Back

Generally, as atomic number increases, atomic radius decreases across a period and increases down a group.

Front

What is the effect of adding energy levels on atomic size?

Back

Adding energy levels increases the size of the atom, resulting in a larger atomic radius.

Front

What is the significance of electron configuration in understanding atomic radius?

Back

Electron configuration helps explain the distribution of electrons in an atom, which influences atomic size and reactivity.
