Wiht increasing atomic number in a certain period

The electronegativity of elements varies with increase in atomic number in groups and periods as

With the increases in atomic number in period

Ionic radii "________" with increases in atomic number in a period and "_______" in a group.

Ionic radii "________" with increases in atomic number in a period and "_______" in a group.

Which of the following properties show gradual decrease with increase in atomic number across a period in the periodic table?

Select the properties which increases regularly with increase in atomic number in atomic number in first group elements of modern periodic table

The atomic radii of three elements A, B and C of a periodic table are 186 pm, 104 pm and 143 pm respectively. Giving a reason, arrange these elements in the increasing order of atomic numbers in the period.

Assertion (A) : It is a better way of arranging the elements in the periodic table is according to the increasing atomic number. Reason (R) : This arrangement. according to increasing atomic number eliminated the problem of anomalous series.

How do atomic structures (electron arrangement) change in a period with increase in atomic numbers, moving left to right?
