Alithium atom has positively charged protons and negatively charged electrons. the sum of the charges represents the charge of the lithium atom. find the charge of the atom.

The answer to your question is:  zero

Step-by-step explanation:

# of protons = 3     they are in the nucleus (blue)

# of electrons = 3   they are in red

Charge = protons + electrons

Charge = +3 + (-3)

Charge = +3 - 3

Charge = 0    

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
