Protons : positive charge , about same mass as neutrons , in the nucleus
neutrons : no charge , about the same mass as a proton , in the nucleus
electrons : negative charge , less mass than protons and neutrons , in orbitals outside of the nucleus
1mol aluminium chloride gives 1mol aluminium and 3mol chloride
density equals mass divided by volume
d=m/v
m=v*d
=78.3*2.7
=211.41grams
Answer:
Hi ,
Answer:
A chemical energy is changed to a electrical energy
Answer:
d.have a mass of 1 amu..
Explanation:
Does not match a as the answer for a is electrons B.electron circle around the nucleus because neutrons are inside the nucleus.C.proton and neutrons make the nucleus so the only answer left is .d .which is correct
Answer:
the positive charges of the nuclei and the negative charges of delocalized electrons
Explanation:
The interatomic forces that joins a piece of metal atoms together are the positive charges of the nuclei and the negative charges of delocalized electrons.
This bond type is the metallic bond.
- The metallic bond is an attraction between the positive nuclei of all the closely packed atoms in the lattice.
- Also, the electron cloud jointly formed by all the atoms losing their outermost shell electrons.
