The most reactive group of nonmetals is the?
Group 17 (known as Halogens)
What are the relative number of metalloids and nonmetals?
Metalloids are 7 and other nonmetals are 17.
Is group 7a on the periodic table metal non metal or metalloids?
1. After the obsolete USA system group 7A contain nonmetals. 2. After the modern IUPAC rules group 7 contain metals (A and B doesn't exist now).
What happens to non metals across the periodic table?
Moving from left to right across a period, up to but not including the noble gases (group 18), reactivity increases. Moving down a group, the reactivity of the elements decreases. Fluorine is the most reactive element.
