Chemical Properties

Front

Which of the following elements have the smallest ionic Radius?

Back

Oxygen

Front

As you move across the periodic table from left to right, the atomic radius decreases. This is because -

Back

the number of protons increases, so attraction to electrons increases.

Front

What is the term that describes the adding of energy levels as you move down the periodic table?

Back

Shielding

Front

Which of the following pairs of elements have similar properties?

Back

Barium and Calcium

Front

What is atomic radius?

Back

The distance from the nucleus of an atom to the outermost shell of electrons.

Front

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

Back

The atomic radius increases due to the addition of energy levels.

Front

What is the trend in ionic radius for elements in the same group?

Back

Ionic radius increases as you move down a group.

Front

What is the effect of increasing nuclear charge on atomic radius?

Back

Increasing nuclear charge pulls electrons closer, decreasing atomic radius.

Front

What is the relationship between atomic radius and electronegativity?

Back

As atomic radius decreases, electronegativity generally increases.
