Answer:
Fe: 23.1%
N: 17.4%
O: 59.5%
Explanation:
You take the grams that each weigh on the periodic table and add it all up. Afterward you create fractions of each over the whole. (Example: Fe/Fe+N+O) then you divide and turn that decimal into a percentage.
Answer:
The three definitions are listed in the explanation.
Explanation:
A nonelectrolyte is a molecular compound that does not consist of ions hence it does not dissociate into ions in solution.
A weak electrolyte is a soluble ionic compound that dissociates only to very small extent into ions in solution.
A strong electrolyte is a soluble ionic compound that dissociates completely into ions when dissolved in water.
The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.
