Periodic Table Trends

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state. It generally increases across a period and decreases down a group in the periodic table.

Front

Which element has the lowest ionization energy in the following options: Barium, Beryllium, Magnesium, Strontium?

Back

Barium has the lowest ionization energy among the given options.

Front

What is atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons. It generally increases down a group and decreases across a period.

Front

Which element has the largest atomic radius in the following options: Potassium, Scandium, Gallium, Arsenic?

Back

Potassium has the largest atomic radius among the given options.

Front

What are isotopes?

Back

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons, resulting in different atomic masses.

Front

How do you determine the natural abundance of isotopes?

Back

Natural abundance is determined by measuring the relative amounts of each isotope in a sample, often using mass spectrometry.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It generally increases across a period and decreases down a group.

Front

Select the sequence of increasing electronegativity: Sn, Ag, I.

Back

The correct sequence of increasing electronegativity is Ag, Sn, I.

Front

Which element has the largest atomic radius in the following options: Cesium, Lithium, Hydrogen, Potassium?

Back

Cesium has the largest atomic radius among the given options.

Front

What is the trend of ionization energy in the periodic table?

Back

Ionization energy generally increases across a period from left to right and decreases down a group.
