Front

What is Electronegativity?

Back

Electronegativity is the ability of an atom to attract or accept electrons.

Front

What is Ionization Energy?

Back

Ionization energy is how much energy it takes to remove an electron from an atom.

Front

Why do atoms get bigger as you move down the periodic table?

Back

Atoms get bigger because they have more energy levels.

Front

Which element has a larger atomic radius than Zinc?

Back

Strontium has a larger atomic radius than Zinc.

Front

Which represents the greatest mass: 7.2x10^-8 gigagrams, 22 kilograms, 1.5x10^12 nanograms, 6x10^-3 megagrams, or 5x10^4 milligrams?

Back

22 kilograms represents the greatest mass.

Front

Define Atomic Radius.

Back

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

Front

What is the trend of Electronegativity in the periodic table?

Back

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

Front

What is the significance of Ionization Energy?

Back

Ionization energy indicates how strongly an atom holds onto its electrons.

Front

Explain the concept of shielding effect.

Back

The shielding effect is the reduction in effective nuclear charge on the electron cloud, due to the presence of other electrons.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy generally decreases.
