Answer:
d Rubidium
Explanation:
The atomic radius of an atom is the distance from the center of the nucleus to its outermost electron.
The atomic radius of elements varies in the periodic table, it increases as you go down in a group and decreases along the period from left to right.
All the elements listed: Hydrogen, Sodium, Lithium and Rubidium belong to the same group in the periodic table (group 1), Since atomic radius increases from top to bottom in a group, Rubidium has the largest atomic radius.
Answer: Option (C) is the correct answer.
Explanation:
Stoichiometric coefficients represents the number of individual atoms involved in the chemical equation.
As a result, stoichiometric coefficients help in balancing the equation because an equation can only become balanced when number of reactant molecules equal the number of product molecules or vice versa.
Therefore, we can conclude that a chemical equation can be used to solve stoichiometry problems provided that it includes the coefficients that are needed for balancing the equation.
