Why is the table of elements called the periodic table? a. It describes the period motion of celestial bodies
b. It describes the periodic recurrence of chemical properties
c. Because the rows are called periods
d. Because the elements are grouped as metals, metalloids, and nonmetals
e. All of these answers are correct

I'm not sure which one is correct but I hope my explanation helps.

Explanation:

It is called the periodic table because of the way the elements are arranged. You'll notice they're in rows and columns. The horizontal rows (which go from left to right) are called 'periods' and the vertical columns (going from up to down) are called 'groups'

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
