What would be its net charge after it has 1% of its electrons removed?

SUMMARY

The net charge of 1.16g of pure gold after removing 1% of its electrons is calculated to be -9.67E-19 C. This is derived from the formula where the charge of an electron is 1.602E-19 C, and the total number of electrons in the gold is determined using Avogadro's number (6.022E23) and the molar mass of gold (196.966 g/mol). The calculation confirms that after the removal of electrons, the gold's net charge transitions from zero to -9.67E-19 C, which can be expressed as 562.477 C for simplicity.

PREREQUISITES
  • Understanding of atomic structure and electron configuration
  • Familiarity with Avogadro's number (6.022E23)

I already posted this but i think i may have a better idea how to do this.

Suppose 1.16g of pure gold has zero net charge. What would be its net charge after it has 1% of its electrons removed?

(1.16g/196.966 g/mol* 6.022E23* 1.602E-19 C) .99= 562.477 C

IS THAT RIGHT?

If you remove X electrons, you remove a charge of (-1.602E-19 C)x. If the net charge is initially zero, it ends up being (1.602E-19 C)x. x = 0.01N, where N is the total number of electrons. N = pq, where p is the number of electrons that a gold atom has, and q is the number of gold atoms in 1.16g of pure gold. q = (m/M)A, where m = 1.16g is the mass of the gold, M is the molar mass of gold, and A is Avogadro's number, 6.022E23. I have a feeling your calculation is wrong. For one, I don't know why you're multiplying by 0.99 (you should be multplying by one minus 0.99). Also, you don't take into account the fact that gold atoms have more than one electron.
 

Yes, your calculation is correct. After removing 1% of its electrons, the net charge of the gold would be 562.477 C. This is because each electron has a charge of 1.602E-19 C, so removing 1% of the electrons would result in a decrease of 0.01*6.022E23*1.602E-19 C = 9.67E19 C. Since the gold initially had zero net charge, the net charge after removing electrons would be -9.67E19 C. However, to simplify the number, we can convert it to a more manageable unit, which is coulombs (C). So, we divide by 1C to get the final answer of 562.477 C.
