Answer:

The atomic radius of calcium is approximately 175

Explanation:

Given that the atomic radius of magnesium = 150 pm

The atomic radius of strontium = 200 pm

Therefore, given that calcium comes in between magnesium and strontium in group 2 of the periodic table, the atomic radius should be half way between the length of the atomic radius of magnesium and strontium, given that the atomic radius is not a fixed quantity

Therefore;

The atomic radius of calcium is approximately given as follows;

The approximate atomic radius (200 + 150)/2 = 175 pm.

HELP!!
wlad13 [49]

Answer:

207.24.

Explanation:

The mass numbers of the 4 isotopes are  82+ 122 = 204,  82 + 125 = 207,

82 + 124 = 206 and 208.

The approximate atomic mass  is worked out by adding the products of their relative abundances  and mass numbers:

0.014*204 + 0.221*207 + 0.241*206 + 0.524*208

= 207.24.
