The reason why Br has a greater magnitude of electron affinity than that of I is that there is a greater attraction between an added electron and the nucleus in Br than in I.
In the periodic table, there are trends that increase down the group and across the period. Electron affinity is a trend that increases across the period but decreases down the group.
Recall that the ability of an atom to accept an electron depends on the size of the atom. The smaller the atom, the greater the attraction between an added electron and the nucleus.
Since Br is smaller than I, there is a greater attraction between an added electron and the nucleus in Br than in I which explains why Br has a greater magnitude of electron affinity than I.

Solutions of thiosulfate are light-sensitive. When exposed to light, they break down into <span>sulfur, sulfite, and sulfate compounds. That is why as much as possible, they must be stored in the dark. This is also the reason why they are stored in amber (dark-colored) bottles.</span>
Since the sample size is below 30, in this case we use
the t statistic. The formula for t score is:
t = (x – u) / (σ / sqrt n)
where,
x = the level l = unknown
u = sample mean = 120 mg / dl
σ = standard deviation = 20 mg / dl
n = sample size or number of results = 5
Using the standard distribution tables for t, we can find
the value of t given the probability (P = 0.15) and degrees of freedom (DOF).
t = 1.036
Going back to the
formula for t score:
1.036 = (x – 120)
/ (20 / sqrt 5)
x = 129.27 mg /
dl = l
BCAA supplements are commonly taken to boost muscle growth and enhance exercise performance.
They may also help with weight loss and reducing fatigue after exercise. This article contains all the most important information about branched-chain amino acids and their benefits.
<h3><u>What are purposes of Branched-chain amino acids (bcaas) ?</u></h3>
- Leucine, isoleucine, and valine are the three essential amino acids that make up the branched-chain amino acids (BCAAs).
- Since they are vital, your body cannot create them on its own and you must get them through food.
- BCAA supplements have been demonstrated to increase muscular mass, lessen muscle pain, and reduce muscle fatigue.
- They have also been used successfully in hospitals to lessen liver disease symptoms and stop or slow down muscle loss.
- However, since the majority of people consume enough BCAAs from their diets, taking supplements is unlikely to provide any further advantages.
