Explanation:
The formula applied here is rydberg's equation (Bohr's equation.)
E = -Rh (1/(nf)^2 - 1/(ni)^2)
where Rh = Rydberg constant = 2.8*10^-18
1 mole = 6.02 * 10^23 particles
nf & ni stand for final & initial principal quantum numbers respectively.
your question lacks the principal quantum numbers.
Answer:
Lower the temperature of the solution
Answer:
Sodium (Na): (.5 point)
22.99+35.453=58.433. 22.99/58.433= 39%
Chlorine (Cl): (.5 point)
22.99+35.453=58.433. 35.453/58.433= 61%

Answer:
B) As you move across the row, the number of electrons increases and reactivity also increases.
Explanation:
The periodic table is arranged in a way that if you go across a period, the number of protons, neutrons, and electrons in an element increases. In terms of reactivity, the most reactive elements are the ones which have a high electronegativity. The electronegativity of the elements increases as you travel to the right and upwards on the periodic table.
