the number of atom present in the molecule is given by the Avogadro number that is 6.022×10²³ . For the CO2 , the molecule is made of 3 atom .So for the one mole of CO2 there are 1.8066×10²⁴ atom.

Answer:
3,4,5,6,7,8
Explanation:
Groups 13 - 18 are the main group on the periodic table
The group number corresponds the number of valence electrons they contains.
Valence electrons are the number of electrons in the outermost shell of an atom.
So group 13 - 18 corresponds to a valency of 3,4,5,6,7,8.
Groups with a valency of 8 are the noble gases.
The statement is true. If a mineral lacks the presence of iron in it then it will be generally dimagnetic. It means non iron minerals do not show magnetic property in general. There are some minerals like serpentine do show some magnetic susceptibility, however this is negligible as compared to iron minerals hence the ores with no magnetic are generally diamagnetic.
