Periodic table and its properties I

Periodic properties and their variations in groups and periods, definition and trends in atomic size, metallic character, non-metallic character, ionisation potential electron affinity and electronegativity

1 / 10

Which element is most likely to have a high electron affinity value?

Sodium (Na)

Chlorine (Cl)

Magnesium (Mg)

Phosphorus (P)

2 / 10

The second ionization energy of an element is always greater than the first ionization energy because:

The electron is removed from a higher energy level

The electron is removed from a more stable configuration

The remaining electrons experience a stronger nuclear attraction

The remaining electrons are further from the nucleus

3 / 10

Which of the following elements exhibits the least metallic character?

Carbon (C)

Beryllium (Be)

Nitrogen (N)

Fluorine (F)

4 / 10

Which of the following trends is observed as you move down Group 17 (the halogens) in the periodic table?

Electronegativity increases

Atomic size decreases

Ionization energy decreases

Metallic character increases

5 / 10

The ionization potential of an element is the energy required to:

Add an electron to an atom

Remove an electron from a neutral atom

Remove an electron from an ion

Add a proton to the nucleus

6 / 10

What is the main reason for the increase in atomic size as you move down a group in the periodic table?

Increase in nuclear charge

Increase in the number of electron shells

Decrease in the number of protons

Increase in the number of neutrons

7 / 10

Which element is expected to have the highest electronegativity?

Fluorine (F)

Oxygen (O)

Chlorine (Cl)

Nitrogen (N)

8 / 10

Which of the following correctly represents the trend in electron affinity across a period in the periodic table?

Decreases from left to right

Increases from left to right

Remains constant across the period

Decreases down the group

9 / 10

Which trend is observed in ionization energy as you move from left to right across a period?

It increases due to increasing nuclear charge

It decreases due to increasing atomic size

It remains constant across the period

It decreases due to increasing metallic character

10 / 10

Which of the following elements has the largest atomic radius?

Sodium (Na)

Potassium (K)

Lithium (Li)

Cesium (Cs)
