An element's atomic number is 5. how many electrons would an atom of this element have? your

Atomic number = number of protons = number of electrons = 5

HOPE THIS WILL HELP YOU

The number of electrons is 5

Atom as a whole is a neutral particle and a neutral atoms of an element contain an equal number of protons and electrons. The number of protons shows an element's atomic number represented by (Z) and distinguishes one element from another. As we said atom is a neutral particle so there must be the equal number of electrons too. So number of protons and electrons are equal. If atomic number is 5 then number of electrons are 5 too.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
