The most loosely held electrons in an atom are called valence electrons.
Answer:
B: Na(s) + Cl2(g) + 3O2(g) = 2NaClO3(s)
Explanation:
We are looking for enthalpy of formation, so we want to see reactance in their natural standard form.
Thus, we want to see the reactance of Na, Cl2 and O2.
The only option that has the correct form of Na, Cl2 and O2 is B.
Na(s) + Cl2(g) + 3O2(g) = 2NaClO3(s)
Explanation:
the sum of PE and KE is mechanical energy this means energy during motion and position I think the answer is motion and stored or it may be internal
Answer:
the number of neutrons in an atom of the element is 10.
Explanation:
neutron: mass # -protons
neutron: 19 (18.9984 (rounded)) - 9
neutron: 19- 9 =10
whole number is equal to the number of protons.
