The lonic radius of the Na'cation is much different than that of the Kication. Choose the one answer that properly identifies their size difference and justifies its fundamental cause O a Both are in the same period, but sodium cation has fewer energy levels with filled orbital. That means the outermost electrons of this ion will be farther from its nucleus, so it has the smaller radius Ob. Both are in the same group, but the potassium cation has a lower nuclear effective charge. That means the electrons of this ion are more strongly attracted to its nucleus, hence the electronic cloud is more compressed, which results in a smaller size. O c. Both are in the same group, but potassium cation has more protons. That means its electrons are pulled with greater strength towards the nucleus, so it has the smaller radius. d. Both are in the same group, but the potassium cation has more core shells with filled orbitals. That means some of the electrons of this ion are more distant Am the nucleus, which results in a bigge radius. 2. Both are in the same group, but potassium cation has more energy levels with filled orbitals. Tha means some of the electrons of this ion are more distant from the nucleus, so this ion has a sm radius.
35 Magnesium hydroxide has different applications. In medicine, for example, it can be used as an antiacid. The reaction with the hydrochloric acid in gastric juices is as follows: Mg(OH)2 (aq) + 2 HCl(a) MgCl2 (aq) + 2 H20 (1) Suppose a person has 250 mL of gastric fluid contents, with a pH of 1.500. If Magnesium hydroxide is administered as a 0.700 M solution, what volume of it will be necessary to neutralize the acid? O a. 267 ml Ob. 11.3 ml c. 22.6 ml d. 5.64 mi e. 534 mi
