What else can I help you with?
Does the first ionization energy increase or decrease when you go down a group?
it increases
What nonmetal in the same group as lead?
Carbon, Silicon (a metalloid), Germanium (a metalloid),
Is helium a metal and a nonmetal?
No, helium is not both a metal and a nonmetal. The element helium (He), along with its cousins in Group 18 of the periodic table of the elements, is a monatomic nonmetal.
What nonmetal is in the same group as pb?
Carbon is in the same group as lead.
Does a nonmetallic character increase or decrease down a group?
Down a group, the number of shells increases, also the atomic size. Thus , the metallic character increase does increase as going DOWN a group. It is easy to remove an electron froman atom of bigger size.
Does the first ionization energy increase or decrease when you go down a group?
it increases
Does the size of atoms increase remain the same or decrease from the top to the bottom of a group of elements?
yes
What is electron affinity . write down its trend in periods and group?
The electronegativity increase in a period from left to right; in a group decrease by descending.
What is the group trend in the first ionization energies and why?
1. The ionization energy decrease down in the group.2. The cause is that the distance between the nucleus and the electron shell increase and the needed energy to extract an electron decrease.
Is sulfur a metal nonmetal or metaloid?
Sulfur is classified as a nonmetal. It is a nonmetallic element found in group 16 of the periodic table.
Is chlorine a main group metal?
No. Chlorine is a main group element, but is a nonmetal in the halogen family (group 17).
What nonmetal in the same group as lead?
Carbon, Silicon (a metalloid), Germanium (a metalloid),
Is helium a metal and a nonmetal?
No, helium is not both a metal and a nonmetal. The element helium (He), along with its cousins in Group 18 of the periodic table of the elements, is a monatomic nonmetal.
What nonmetal is in the same group as pb?
Carbon is in the same group as lead.
What is a nonmetal group in the periodic table that is reactive?
group 17, halogens
Does a nonmetallic character increase or decrease down a group?
Down a group, the number of shells increases, also the atomic size. Thus , the metallic character increase does increase as going DOWN a group. It is easy to remove an electron froman atom of bigger size.
Is helium a metal nonmetal or metalloid?
Helium is a nonmetal. It has properties that classify it as a noble gas, which is a group of nonmetals that are generally unreactive.
