2 valence electrons
Explanation:
Most transition metals have 2 valence electrons. Valence electrons are the sum total of all the electrons in the highest energy level (principal quantum number n). Most transition metals have an electron configuration that is ns2(n−1)d , so those ns2 electrons are the valence electrons.
Answer is: sodium (Na) and iodine (I₂).
<span>
First ionic bonds in this salt are separeted
because of heat:
</span>NaI(l) → Na⁺(l) + I⁻(l).
Reaction of reduction
at cathode(-): Na⁺(l) + e⁻ → Na(l) /×2.
2Na⁺(l) + 2e⁻ → 2Na(l).
Reaction of oxidation
at anode(+): 2I⁻(l) → I₂(l) + 2e⁻.
The anode is positive
and the cathode is negative.
Answer:
Three things that rely on the sun for energy is coal,oil, and natural gases
Explanation:
We use engery too cook our food that's an example of how gases are used.
We run our cars .Cars use oil.
And we use electricity for lights. You need coal for the electricity
Fusion releases less energy than fission
fusion most commonly combines heavy isotopes of hydrogen into helium.
Explanation:
Nuclear fusion is a form of reaction that involves the combination of two light nuclei to form one that is heavier in mass.
The other form is nuclear fission which is the splitting of heavier nuclei either spontaneously or when bombarded with other nuclei.
- Nuclear fusion reactions in the core of stars powers the universe.
- The reactions produces a huge amount of energy of a greater and massive order than fission reaction.
- Small nuclei are involved in nuclear fusion and not the large ones.
- Nuclear fusion degenerates into series of chain reactions that are extremely difficult to control.
