Carbon has a neutral overall charge, an atomic mass of about 12 and an atomic number of 6. How many electrons does carbon have?

Artist 52 [7]

For the atom to be neutral, it must have the same number of electrons and protons. The aromic number indicates the number of protons. Since Carbon has 6 protons, it would have to have 6 electrons for it to be neutral

White phosphorus melts and then vaporizes at high temperatures. The gas effuses at a rate that is 0.404 times that of neon in the same apparatus under the same conditions-There are 4 atoms of P in the molecule

Explanation:

Ar=30,97g/mol

$R_{Px$ / $R_Ne}$ = $\sqrt{Mr(Ne)/Mr(Px)}$ =0,404

0,404= $\sqrt{20,18/30,97*x}$

$0,404^{2}$ =20,18/30,97*x

X=20,18/30,97*0,163

X=4

There are 4 atoms of P in the molecule

*WILL MARK BRAINLIEST!<br> Why is it difficult for us to use fusion reactions to produce energy?

kolbaska11 [484]

Fusion occurs constantly on our sun, which produces most of its energy via the nuclear fusion of hydrogen into helium. Neither do fusion reactions produce the large amounts of dangerous radioactive waste that fission reactions do. That's why it's such a dreamy source of energy.
