If you have 5 protons and 6 neutrons, how many electrons would you add to make a neutral atom?

Mathematics

Goshia [24]3 years ago

Answer:

The correct option is;

5 electrons

Step-by-step explanation:

The charge of the proton is equal to 1.602 × 10⁻¹⁹C while the charge of one electron is -1.602 × 10⁻¹⁹C

Therefore, given that the atom is to be electrically neutral, we have;

The initial charge of the atom = 5 × 1.602 × 10⁻¹⁹C = 8.01 × 10⁻¹⁹C

The charge of the added electron + The charge of the present proton = 0

Therefore;

The charge of the added electron + 8.01 × 10⁻¹⁹C = 0

The charge of the added electrons = 0 - 8.01 × 10⁻¹⁹C = -8.01 × 10⁻¹⁹C

The charge of one electron = -1.602 × 10⁻¹⁹C

The number of electrons = The charge of the added electrons/(The charge of one electron)

The number of electrons = -8.01 × 10⁻¹⁹C/(-1.602 × 10⁻¹⁹C) = 5 electrons

The number of electrons to be added = 5 electrons.

-2.3 + 10.8 + (-8.4)
spayn [35]

Answer:

.1

Step-by-step explanation:

Try and take it step by step.

-2.3 + 10.8 + (-8.4)

First let's rearrange and combine the negatives.

-2.3 + (-8.4) + 10.8

-2.3 + (-8.4) = - 10.7

Let's rewrite

10.8 - 10.7  and solve!

10.8 - 10.7 = .1

A line has a slope of –3 and a y-intercept of (0, –1). What is the equation of the line that is parallel to the given line and p
givi [52]
Well, the first line has a slope of -3, and runs through 0, -1.

a line parallel to that one, will have the same exact slope of -3.

now, we know about this other parallel line that it runs through -3,1, and of course, since is parallel, it has a slope of -3

\bf \begin{array}{ccccccccc}&#10;&&x_1&&y_1\\&#10;&&(~ -3 &,& 1~)&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope =  m\implies -3&#10;\\\\\\&#10;% point-slope intercept&#10;\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-1=-3[x-(-3)]&#10;\\\\\\&#10;y-1=-3(x+3)&#10;\implies &#10;y-1=-3x-9\implies y=-3x-8
