Question

what element in the second period has the largest atomic radius? carbon lithium neon potassium question 10 2.5 pts each period in the periodic table corresponds to a(n) ____. principal energy level energy sublevel orbital suborbital

Explanation:

• For the first question:
• Atomic radius decreases across a period (from left to right) due to increasing nuclear charge which pulls electrons closer. Lithium (Li) is on the far - left of the second period. Carbon (C) is to the right of Li, neon (Ne) is a noble gas (with a different radius measurement method but still smaller than Li in the context of general trends), and potassium (K) is in the fourth period.
• For the second question:
• In the periodic table, each period corresponds to a principal energy level. As we move down the periodic table (to higher - numbered periods), the principal energy level of the outermost electrons increases. Energy sublevels (like s, p, d, f) are within principal energy levels. Orbitals are within sublevels, and sub - orbitals is not a standard term in this context.

Answer:

• First question: lithium
• Second question: principal energy level
