What action would you expect an atom of Aluminum to undergo?

KATRIN_1 [288]

Answer:

C. Lose three electrons to have a full outer shell

Explanation:

Al is in Group 13 of the Periodic Table, so it has three valence electrons.

It must either lose three electrons or gain five to achieve a stable octet.

It is easier to lose three electrons than it is to gain five, so Al loses three electrons.

D. is wrong, for the same reason.

A. is wrong. If Al lost three electrons, it would be breaking into a stable inner shell.

C. is wrong. Al is a metal, so it will lose electrons in a reaction.

calculate atomic weight of silver which has two isotopes with the following properties : silver-107 (106.91 amu, 51.84% natural

Julli [10]

Answer: The atomic weight of silver is 107.87 amu

Explanation:

Mass of isotope silver-107 = 106.91 amu

% abundance of isotope silver -107 = 51.84% = $\frac{51.84}{100}=0.5184$

Mass of isotope silver-109 = 108.90 amu

% abundance of isotope silver-109 = 48.16% = $\frac{48.16}{100}=0.4816$

Formula used for average atomic mass of an element :

$\text{ Average atomic mass of an element}=\sum(\text{atomic mass of an isotopes}\times {{\text { fractional abundance}})$

$A=\sum[(106.91\times 0.5184)+(108.90\times 0.4816)]$

$A=107.87amu$

Thus atomic weight of silver is 107.87 amu
