Atomic mass :

29.5 * 203 + 70.5 * 205 / 100 = 

5988.5 + 14452.5 / 100 = 

20441 / 100 = 204.41 u

atomic mass of Thallium <span>204.41 u
</span>
hope this helps!

Answer:

The answer is "42537.93 \ C".

Explanation:

Molar mass : Z_n = 65.38 \ \frac{g}{mol}\\\\

\to Zn^{2+} + 2e^{-} = Zn\\\\

\therefore\\\\ \to 65.38 \ g \ of\  Z_n  \ require: \\\\ \to 2 \times 96500\  C\\\\\to 14.41 \ g\  require,\\\\ \to \frac{(14.41 \times 2 \times 96500)}{65.38} \ \frac{g}{mol} = 42537.93 \ C

Organize the following elements in order of increasing atomic radius (Ge, He, Sr, O, Ba)
Katen [24]

Answer:

He

O

Ge

Sr

Ba

Explanation:

An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements.

In general, the size of an atom will decrease as you move from left to the right of a certain period.
