Answer:
P^3- > S^2- > Cl^- > K^+ > Sc^3+
Explanation:
Ionic radii is an example of physical properties of Periodicity.
The size of an atom's ion is difficult to estimate because of the electronic distribution and arrangement. This is due to the fact that the atom' ion have no definite outer boundary. In order to circumvent this problem, the atom's ion is estimated in a crystal lattice in terms of its ionic radii.
Ionic radii is taken as half the distance between atomic ions in a crystal lattice. Across a period in the periodic table , ionic radii decreases progressively from left to right.
Down the group, the ionic radius increases from top to bottom.
So the arrangement of the given elements from largest to smallest radius in the decreasing order of ionic radius will be:
P^3- > S^2- > Cl^- > K^+ > Sc^3+

Answer:
- , and
This solution is likely to be basic.
Assumption: this solution is under room temperature, where .
Explanation:
The concentration of hydronium ions in the solution can be found from the value. This relationship does not depends on temperature.
.
The question states that for this solution, . Apply the relationship between , , and . Note that the value of is dependent on the temperature of the solution.
.
In other words,
.
In other words, this solution is basic.
Explanation:
An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation—a positively charged ion. The atom gaining one or more electron becomes an anion—a negatively charged ion.
Titanium. It is the hardest metal so would be able to scratch it easily
