<span>A carbon - 12 atom and a
regular carbon atom would have the same number of protons which is 6. So a
carbon - 12 atom would have 6 protons. Both, however, would differ in the
number of neutrons. Carbon - 12 atom has 6 neutrons. To determine the mass
defect of a carbon - 12 atom, we have to add the total mass of protons and the
total mass of neutrons and subtract the known mass of a carbon - 12 atom. That
would be like this.<span>
6
(1.00728 amu) + 6 (1.00866 amu) = x
<span>6.04368
amu<span> + 6.05196 amu = x</span></span>
12.09564
amu = x
Then
subtract it with 12 amu to get the defect mass
12.09564
amu - 12.00000 amu = y
0.09564
amu = y
<span>So the
defect mass would be 0.09564 amu.</span></span></span>
Answer: The two main types of chemical bonds are ionic and covalent bonds. An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms.Jan 23, 2020
Explanation: Hope this helped!!!!
Answer:
Number of delocalized electrons
Explanation:
Magnesium has more delocalized electrons compared to sodium and this accounts for the higher melting point.
- When magnesium atoms comes together to form a metallic bonds, they have more network of delocalized electrons.
- There is more pull for the localized electrons due to the nuclear charge on the nucleus.
- This strong intermolecular metallic bond increases the melting point of magnesium.
