The metallic bond between gold atoms makes it possible to create extremely thin sheets.
Atoms of the same element or atoms from different elements can form three types of bonds:
- Covalent bonds.
- Ionic bonds.
- Metallic bonds.
In the case of metals such as gold, the most common type of bond is the metallic bond. This bond:
- Is a strong bond.
- Involves the free movement of electrons between atoms.
- Makes metals highly malleable.
These characteristics explain the reason why it is possible to create extremely thin sheets as the material will not easily break due to the strong attraction between the atoms.

Hey there!
I am not the greatest in this subject but I believe that 2C2H2+502 is balanced!
If i am incorrect, I am very sorry and would love any feedback!
Hope i made your day easier.
Have a nice day and happy Halloween!
You would use the formula:
n =
Where m is the mass, and M is molar mass (the periodic table would be used for this)
In this case, we need to rearrange the formula to find m
m = nM
= 5.40 x 6.941
= 37.5g
Hope this helped! Ask me if there's any part of the working you don't understand :)
Answer: 121.95587 g/mol
Explanation:
- The atomic mass of aluminum is 26.98154 g/mol.
- The atomic mass of phosphorous is 30.97673 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
Therefore, the molecular mass is:
Answer:
1st group (or 1A in some tables)
Explanation:
Mass number = number protons + number neutrons
23 = number protons + 12
number protons = 23 - 12= 11, so atomic number is 11.
Sodium (Na) has an atomic number 11.
Sodium is in the 1 group, or 1A group in some Periodic tables.
