As you move from left to right across a period, what happens to the atomic radii?
GrogVix [38]

Answer:

They decrease, because of the stronger effective nuclear charge.

Explanation:

  • Atomic radii decreases from left to right across a period.
  • This is due to the increase in the no. of protons and electrons through the period.
  • One proton has a greater effect than one electron.
  • So, electrons are attracted towards the nucleus and resulting in a smaller atomic radii.

<em>Thus, the right choice is: They decrease, because of the stronger effective nuclear charge.</em>
