How many electrons does an isotope of Ca-41 have? A
21

B
61

C
41

D
20

Ca-41 has 20 electrons

The elements in nature have several types of isotopes

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Calcium is an alkaline earth metal element that is in group 2 and has the atomic number 20

The isotope of Ca-41 :

Number of protons=number of electrons=number of atoms(neutral atom)

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

have a great day because if you dont you and i will be sad
