Answer:
2s2 2p5
Rb < Sr< Sn< Te<I
Explanation:
Electron affinity is the ability of an atom to accept electrons to form negative ions.
Electron affinity is a periodic trend that decreases down the group but increases across the period.
This accounts for the trends observed in the answer. The atom having the electronic configuration, 2s2 2p5 must be a halogen and it exhibits the highest value of electron affinity.
Also, since electron affinity increases across the period, the electron affinities of the elements increases. Therefore, the arrangement of atoms as shown in the answer depends on increasing electron affinity.
Explanation believe the answer is A. Average.

Answer:plz brainly me;)
Your answer is "A" Conductors
Nonmetals include common gasses that are found in the atmosphere, such as nitrogen and oxygen, as well as sulfur (S) and carbon too. Nonmetals are usually not good conductors of heat and electricity.
