Locate Antimony, Sb, on a periodic table. Antimony has two common isotopes, Sb-120 and Sb-124. What are the percent abundances of each isotope?

Explanation:

Antimony Sb, is located on the 5th group on the periodic table with other elements such as Nitrogen, phosphorus, arsenic, bismuth and moscovium.

Its electronic configuration is:

             2, 8, 18, 18, 5

The percent abundances of each isotope is;

 Sb - 121  = 57.21%

 Sb  - 123  =  42.79%

14 days is the half-life of phosphorus-32

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
