Due to its bigger size compared to bromide ions, iodide ions have a poorer charge-to-volume ratio.
Iodide ion has a lower ratio of charge to volume because iodine is bigger and has the same charge as both other ions. Ca ions have a lower ratio of charge to volume than Sc ions because they are larger in size and have less charge than Sc ions. Due to its bigger size compared to potassium ions, bromide ions have a poorer charge-to-volume ratio. Sulfate ions have a larger charge density than ClO4 ions do because sulfate ions have more charge than ClO4 ions do.

31, 31, 40. An atom of _31^71Ga has 31 electrons, 31 protons, and
40 neutrons.
The atomic number is 31, so the atom has<em> </em>31 protons (+).
If the atom is neutral, it must contain 31 electrons (-).
Mass number = protons + neutrons or
A = p + n
71 = 31 + n
n = 71- 31 = 40 neutrons
The answer would be C8H18, or octane. Column chromatography is a separation technique that works off of polarity. The stationary phase, in column chromatography, are non-modified silica gels. Silica gels are normally polar. This means the solvent that will elute first are non-polar molecules...then polar molecules. The polar silica gels have a stronger interaction with polar molecules like CH3OH, and therefore will lag the solvent. Additionally, as you decrease the carbons, in hydrocarbons, the molecule becomes more polar. This is not C6H6 isn't the answer and octane is.
Answer:
two transitions elements are iron and cobalt
