Question

IF an element.'X' has mass number 14 and it has 7 neutrons, then write its representation​

Answer 1

Answer:

since mass is 14 and X has 7 neutrons therefore ,

no. of protons=14-7=7

and we know that atomic no.=no.protons present

so, its representation is-

¹⁴7X

look I cannot write 7 in superscript so I am telling you that before that don't be confuse it is not 7x it the atomic no. in the superscript. I hope you get that
