On the periodic table, the trend in ionization energy is the opposite of the trend in atomic size. True or False?

1 answer:

6 0

False.
Your initial ionization numbers are 1, 2, 3, +/- 4, -3, -2, -1. This does not trend opposite nor coincides with the atomic mass. As atomic mass is constantly increasing within the periodic table, there is not true correlation between ionization and atomic mass.

How many atoms are in 20.6 moles of curium

Harman [31]

Answer: 1.24 × 10^25

Explanation:

$\frac{20.6 moles}{1}$ × $\frac{6.022 * 10^{24} }{1 Mole}$

Using our knowledge in unit conversions, we know the mole units cancel each other out and all there's left is the atom unit. From here we can multiply the fractions and eventually we end with the number 124.0532 × 10^23

According to the scientific notation rules, the number to the left of the decimal cannot exceed 10 so we have to move the decimal to the left two spaces. With this change, we also have to change the exponent of the 10. Because we moved the decimal point two spaces to the left, that means we have 10^25.
