The mass of 2.47 moles of fluorine atom is 46.9 g
calculation
mass of Fluorine= moles x molar mass
moles = 2.47 moles
molar mass of fluorine = 18.998 g/mol
mass is therefore= 2.47 moles x 18.008 g/mol = 46.9 g
Answer: heyyyooo
The bond polarity for each bond in a BH3 molecule is polar, due to the difference in electronegativities of the B and H atom. The molecular shape is trigonal planar, and the molecule is non-polar - because due to the symmetry of the molecule, the polarities cancel out.

Answer:
Generally, the atomic radius decreases across a period from left to right and increases down a given group. ... This causes the atomic radius to decrease. Moving down a group in the periodic table, the number of electrons and filled electron shells increases, but the number of valence electrons remains the same.
