Answer:

If the protons in the atom outnumber the  electrons, the isotope has more positive charges than negative charges but If the number of electrons exceeds the number of protons, the ion charge will be negative.

The charge of an isotope is defined by how many more protons there are than electrons.

Or the other way around.

For example if there are 4 protons and 2 electrons, the ion charge is +2 because there are more protons.

If there are 4 electrons and 2 protons, the ion charge is -2 because there are more electrons.

How much time would it take to distribute one avagadro's number of wheat grains if 10^10 grains are A)1.9*10^2 years B)1.9*10^10
Makovka662 [10]

Answer:

It takes  1.9 \times 10^{6} years to distribute all the grains.

Explanation:

In one second, 10^{10} grains of wheat are distributed.

We are supposed to find the time it would take to Distribute Avogadro number of grains.

1 avogadro number = 6.022 \times 10^{23}

Number of grains distributed in 1 day = 86400 \times 10^{10}

                                                             = 8.64 \times 10^{14}

Number of grains distributed in 1 year= 8.64 \times 10^{14} \times 365

                                 = 3.1536 \times 10^{17}

Time taken = \frac{Number of grains to be distributed}{grains distributed in 1 year}

            = \frac {6.022 \times 10^{23}}{3.1536\times 10^{17}}

            = 1.9 \times 10^{6}
