the number of energy levels
I hope this helps you. I did a lot of reasearch to find the answer. Please mark me Brainliest! Thank you.
Answer:
C. Sb has a lower ionization energy and a lower electronegativity than I.
Explanation:
The chemical elements present higher ionization energy the higher and to the right of the periodic table they are.
Electronegativity usually increases from left to right over a period of the periodic table and from top to bottom in the groups.
Answer:
the empirical formula gives the simplest ratio of whole numbers of components in the compound. Molecular formula gives the actual composition of elements in the compound.
Explanation:
empirical formula - CH₂O
Mass of one empirical unit = 12 + (1x2) + 16 = 30 a.m.u
We have to next calculate how many empirical units make up the molecular formula. For that we have to divide molecular mass by mass of one empirical unit.
Number of empirical units = 180 a.m.u / 30 = 6
There are 6 empirical units
Therefore molecular formula = 6 x(CH₂O) = C₆H₁₂O₆
Molecular formula = C₆H₁₂O₆
