To find the number of excess electrons, we need to calculate the charge of a single electron and then divide the total excess charge by the charge of a single electron.

The charge of a single electron is represented by the elementary charge, which is approximately equal to 1.6 × 10^-19 C.

Let's calculate the number of excess electrons:

Number of excess electrons = Total excess charge / Charge of a single electron

Number of excess electrons = (-8.6 × 10^-18 C) / (1.6 × 10^-19C)

Number of excess electrons ≈ -5.375

Since we can't have a negative number of electrons, let's take the absolute value:

Number of excess electrons ≈ 5.375

Therefore, the object has approximately 5.375 excess electrons.

To determine the number of excess electrons an object has, you can use the elementary charge, e. The elementary charge, e, is the charge of a single electron and is approximately 1.6 x 10^-19 coulombs (C).

Given an excess charge of -8.6 x 10^-18 C, we can divide this value by the elementary charge to find the number of excess electrons.

Number of excess electrons = (excess charge) / (elementary charge)

Plugging in the values:
Number of excess electrons = (-8.6 x 10^-18 C) / (1.6 x 10^-19 C)

Now, divide the numerator by the denominator:
Number of excess electrons = -8.6 x 10^-18 C / 1.6 x 10^-19 C

We can simplify the division by dividing the coefficients and subtracting the exponents of the powers of 10:
Number of excess electrons = -8.6 / 1.6 x 10^(-18 - (-19)) electrons

Simplifying:
Number of excess electrons = -8.6 / 1.6 x 10^1 electrons
Number of excess electrons = -5.375 x 10^1 electrons

Therefore, the object has approximately -53.75 excess electrons. Note that the negative sign indicates an excess of electrons, while a positive sign would indicate an excess of protons.
