The remaining 3 % are nanomaterials made from e.g. aluminium oxide, barium titanate, titanium dioxide, cerium oxide and zinc oxide. Carbon nanotubes, graphene and fullerenes have annual production amounts in the hundred tonnes range. Nanosilver is estimated to be produced in about 20 tonnes per year.
I looked this up but hope it helps
Answer:
A family in the periodic table is a group of related elements.
Explanation:
We have that the Electronegative difference of 2.15 basically makes ionic bonds
Ionic bonds is to be formed
<h3>Bonding</h3>
Generally, the common electronegativity of the team 1 <u>factors </u>are 0.84 and the common <em>electronegativity </em>of the team 17 factors are 2.99.
Group 17 factors are an awful lot greater electronegative than Group 1 elements.
Group 17 consists of F, Cl, Br and I,Group 1 factor that is Na loses 1 electron from its outermost orbit and varieties Na+ cation.
Group 17 Element that is Cl accepts 1 electron in its outermost orbit and Creates Cl- anion. Now, Na+ cation and Cl- anion combines collectively by using ionic bonds.
Hence, the electronegative difference
(2.99-0.84)=2.15
Electronegative difference of 2.15 basically makes ionic bonds
