Bernice draws an oxygen atom. She draws a small circle for the nucleus. Inside of the circle, she draws plus signs for protons and dots for neutrons. Around the nucleus she uses minus signs to represent electrons. Which statements are true about her drawing? Select all that apply.
A
There are eight protons in the nucleus.

B
There are sixteen protons in the nucleus.

C
There are eight neutrons in the nucleus.

D
There are sixteen neutrons in the nucleus.

E
There are sixteen electrons in her drawing.

F
There are fourteen electrons in her drawing.

Answer

It should be A and C

Explanation:

because oxygen is number 8 in the periodic table of elements and has a atomic weight of 15.999 you use those numbers to figure out what is true between those.

The 8 for oxygen goes for the number of electrons and proton and to find neutrons u round the 15.999 up which now make it 16 and subtract it by the 8 now you have 8 protons, 8 neutrons, and 8 electrons

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

answer: option c.
