On the periodic table, atomic radius generally decreases as you move from left to right across a period (due to increasing nuclear charge) and increases as you move down a group (due to the increasing number of electron shells). In a group, the size of an atom increases as one proceeds from top to bottom. This is due to the successive addition of shells as one move from one period to the next in a group.
(8.083.03 + 59.59% of 839.83) ÷ 16.06 × 24.04 = ?3 + 1012.12
√(195.99 X 8.99 X 15.87) X ³√124.99 = ? X 11.99
[34.01 × 18.98 – 12 × √576.03 – 198] ÷ 3.95 = ?
(359.92÷24.02)+(230.04÷5)=?% of 210.0-86.1
(√360.99 + 161.14) ÷ 5× 249.98 = ?
(2100.23 ÷ 34.98) + (864.32 ÷ 23.9) + 1854.11 =?
³√? × 33.97 + 59.99 × 28.9 – 48.98 × 21.42 = 1085.344
? = 65.78² ÷ (5.01⁵ + 7.02 × 33.33) + 33.33% of (290.88 × 23.09)
