An atom of sodium-23 (Na-23) has a net charge of +1. Identify the number of protons, neutrons, and electrons in the atom. Then, explain how you determined the number of each type of particle. Use the periodic table to help you.

Protons = 11  Electrons = 10  Neutrons = 12

Explanation:

Sodium's atomic number is 11. The atomic number is determined by the number of protons in an atom. Since protons have a charge of +1 you would need 1 less electron than proton. Finally, to find the number of neutrons, you subtract the atomic number FROM the atomic mass. The atomic mass of Na23 is 23. Subtract 11 from 23 and you get 12.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

its first and third is your answer i did the qustion the fourth isnt right
