What has an atomic mass of 14 and a -1 charge

If the charge is positive, subtract that number from the atomic number to get the number of electrons. You have more protons.

...

Determining the number of electrons-

a) 28Siprotons = 14, electrons = 14, neutrons = 14

14

b) 197Aub p = 79, e = 79, n = 118

79

c) 40Arc p = 18, e = 18, n = 22

18

d)     64     Cu  d  p = 29, e = 29, n = 35

29

e)    39      Ke  p = 19, e = 19, n = 20

  19

f)   133      Csf   p = 55, e = 55, n = 78  

55

THIS ANSWER HELPS YOU..

Explanation:

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
