Which element has 38 electrons, is found in group 2, period 5? fun fact: this element gives us the bright red colors in fireworks!

 The element  that has 38  electrons  is Sr( Strontium)

  explanation

The atomic number of element is  equal  to number of protons.\

 The  number  of proton is equal  to number  of electrons, therefore if the has 38  electron it has 38  protons  and is in atomic number 38

Strontium  is in group 2  and  in period  5  and  is in atomic number 38

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
