how many neutrons are in an atom of copper? round
your answer to the nearest whole number.

Copper (Cu)

Neutrons‎: ‎35  Electrons‎: ‎29

Protons‎: ‎29Atomic Number‎: ‎29

Explanation:

Atomic number of copper is 29. The atomic number of an atom is determined by the number of protons in the nucleus. Therefore, there are 29 protons in an atom of copper. In a neutral atom, there are equal number of protons and electrons. Therefore, there are 29 electrons in a copper atom. Mass number of copper is 64.

Number of protons + Number of neutrons = mass number.

Therefore, number of neutrons = 63 -29 = 35

In order to calculate the voltage difference in the circuit, we need to look at the equation: V=IR.

In the equation:

V= Voltage

I= Current

R= Resistance.

Assuming we know this, We will plug it into an equation to find our voltage.

V=(.50a)x(24Ω)

If we solve for V, Your final answer will be: 12v (or 12 volts)
