Question

multiple-choice question what is the trend in atomic size as you proceed down a group? it decreases it stays the same it increases rewatch

Explanation:

In the periodic table, as we move down a group (vertical column), each element has an additional electron shell compared to the one above it. More electron shells mean the atomic radius (and thus atomic size) increases because the outermost electrons are further from the nucleus. So the atomic size trend down a group is that it increases.

Answer:

C. It increases (assuming the options are labeled A, B, C as "It decreases", "It stays the same", "It increases" respectively; if the third option's identifier is different, adjust to match, e.g., if the third checkbox is the one with "It increases", state the option with its text like "The option 'It increases' (the third option)")
