Since this is Argon it would be a noble gas
Answer:
% of mass of electrons in C = 0.0272
Explanation:
Atomic no. of carbon = 6
So, no. of electron = 6
Mass of an electron = 
Mass of 6 electrons = 
Mass of C = 12.0107 u
% of mass of electrons in C = 
% of mass of electrons in C = 
To calculate the number of moles, simply take the ratio of mass and molar mass. The molar mass of Iron (Fe) is equal to 55.85 g/mol.Therefore the total number of moles is:
moles Fe = 25.7 g / (55.85 g / mol)
moles Fe = 0.46 mole
Answer:
Explanation:The main difference between ionic covalent and metallic bonds is their formation; ionic bonds form when one atom provides electrons to another atom whereas covalent bonds form when two atom shares their valence electrons and metallic bonds form when a variable number of atoms share a variable number of electrons in a metal lattice.
Possibly the amount of electrons and energy levels in which the electrons reside
