11. Which of the following statements is true? a. Atomic radii increase from left to right across a period and increase going down a group. b. Atomic radii increase from left to right across a period and decrease going down a group. c. Atomic radii decrease from left to right across a period and decrease going down a group d. Atomic radii decrease from left to right across a group and increase going down a group 12. Which of the following statements regarding ionization energy is false? a. The ionization energy for an atom is the minimum energy needed to remove the highest- b. The ionization energy for an atom is the minimum energy needed to add an electron to an C. Ionization energies tend to decrease when going down any column in the periodic table. energy electron from an atom in the gaseous state. atom in the gaseous state d. lonization energies tend to increase when going across a period in the periodic table. e. More than one answer is false. 13. Which of the following statements regarding electron affinity is false? Electron affinity is the process of removing an electron from a neutral atom in the gaseous state. Electron affinity is the process of adding an electron to a negative anion in the gaseous state a. b. c. If the electron affinity is a large negative number, then a stable species was formed. d. More than one of the above is false e. None of the above is false.Explanation / Answer
The atomic radii decrease along left to right due to effective nuclear charge.and due to increases in shell from top to bottom ionic radii increases
Option c is correct...
12) IE is energy required to remove an electron so option B is incorrect. Furthermore ,the IE increases along the period and decreases along the group..
Only option b is false....
13)option A is incorrect since EA is energy to add an electro...
Higher negative value shows atom can easily get an electronic to form anion and stable species
Option A is incorrect
