A particular atom of calcium has 20 protons, 21 neutrons, and 19 electrons. what is the electrical charge on this atom?
Fiesta28 [93]

In a particular calcium atom, number of protons are 20, number of neutrons are 21 and that of electrons are 19. Here, protons are positively charged particles, neutrons are neutral and electrons are negatively charged particles. For a neutral atom, number of protons should be equal to number of electrons. If number of protons are more than number of electrons cation will  form (positive charge) and if number of protons are less than number of electrons anion will form (negative charge).

Here, number of protons are 20 and that of electrons are 19, protons is 1 more than electron thus, Ca will get one positive charge and exist as Ca^{+}. Thus, the electrical charge on the atom will be +1.

Theoretically how many moles of carbonic acid will be produced by the 3.00 g sample of NaHCO3
yaroslaw [1]
NaHCO3 = 22.99 + 1.008 + 16(3) = 83.99 g/mol 
<span>Na = 22.99g/83.99 g weight of molecule =.2727 or 27.27% </span>
<span>3.0 g* .2727 = 0.8211 grams of sodium in sample of NaHCO3 

</span><span>0.8211 grams Na + 1.266 grams Cl = 2.087 grams</span>
