Question

A certain polytomic ion contains 49 protons and 50 electrons. What's the net charge of this ion?

Answer 1

Net charge is -1

Step-by-step explanation:

`{ \sf{net \: charge = p {}^( + ) + {e}^( - ) }} \\ = { \sf{49 + ( - 50)}} \\ = - 1`

Answer 2

the charge is -1

Step-by-step explanation:

because the charge of proton is +and electron -

charge = +49 +(-50)

= -1
