An atom has an atomic number 8 and a mass number 16 .If the atom gains two electrons. What will be the charge of the ion ​

10 21

Step-by-step explanation:

2 with negative charge

Step-by-step explanation:

atomic number 8

mass 16

then the charge of ion will be = 2 negative charge

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
