can you please help with my most recent question :)
Answer:
Element with the smallest radius is Carbon.
Explanation:
In a periodic table, atomic radius increases down the group due to addition of a new shell and decreases across the period from left to right due to increasing nuclear charge.
Due to addition of more electrons in same shell and increase of positive charge in nucleus increases attractive forces between electrons and nucleus hence decreasing size.
Carbon and Lithium are present in same period and hence Carbon has smaller size; Potassium and Bromine are present in same period and hence out of the two, Bromine has smaller size.
On comparing Carbon and Bromine, atomic radius increases down the group hence, Carbon has the smallest radius among the four given elements.
I believe the correct answer is option A. Paré.
Or otherwise known as Ambroise Paré. He was considered one of the "fathers of surgery" for modern forensic pathology. And was known to be a pioneer in surgical techniques on the battlefield using medicine, mostly in the treatment/healing of wounds.
