Question

the size of the negative charge of an electron is exactly the same as the size of the positive charge on a proton what is the overall charge of the heluim atom shown in the diagram .... ? ​

Answer 1

Overall charge of the helium atom is zero

Step-by-step explanation:

this is because we know the charge of an electron is -1 and the charge of a proton is +1.

there is 2 electrons and 2 protons therefore the charges cancel out.

Therefore the charge of a helium atom is zero

( u can also visualize this as -2+2=0 )
