Question
Right or wrong sentence.
Moving from left to right, the size of the atom decreases.
Options
Right
Wrong
Advertisements
Solution
The given sentence is right.
Explanation:
If you mean “moving from left to right across a period of the periodic table”, the sentence is correct: atomic size (atomic radius) generally decreases because the nuclear charge increases while electrons are added to the same shell, so electrons are pulled in closer to the nucleus.
