Which statement correctly compares an atom of Neon-20 and an atom of Sodium-23?

An atom of neon 20 has one fewer proton and one fewer neutrons than an atom of sodium-23.

An atom of neon-20 has one more proton and two fewer neutrons than an atom of sodium-23.

An atom of neon-20 has one fewer proton and two fewer neutrons than an atom of sodium-23.

An atom of neon-20 has one fewer proton and two more neutrons than an atom of sodium-23.

An atom of neon-20 has one fewer proton and two fewer neutrons than an atom of sodium-23.

Explanation:

Neon - 20 and Sodium - 23

Neon - 20

Protons = 10

Neutrons = 10

Sodium - 23

Protons = 11

Neutrons = 12

With the information above and checking the options;

An atom of neon-20 has one fewer proton and two fewer neutrons than an atom of sodium-23.

This option is correct.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

so what is the problem with your lab report and whats the subject of the lab report? i will you
