Answer:
Na⁺
Explanation:
Given parameters:
Number of protons = 11
Number of neutrons = 12
Writing the expression based on sodium ion that lost one electron;
In a neutral sodium atom, the number of protons and electrons are the same. Number of protons are the the positively charged particles in an atom.
Number of electrons are the negatively charged particles.
If an atom loses electron for instance sodium:
Number of electrons = 10
Number of protons = 11
Charge on the atom = 11 - 10 = 1+
So, the symbol of the atom is Na⁺
Answer:
if what you need is the final answer
the final answer is = 0.228 and I think the unit is Liter(L).
Explanation:
The basis of finding the answer to this problem is to know the electronic configuration of Fluorine. That would be: <span>[He] 2s</span>²<span> 2p</span>⁵. The valence electrons, which are the outermost electrons of the atom, are the ones that participate in bonding. <em>Since the highest orbital for F is 2p, that means the highest energy occupied would be 2.</em>
