Answer:
I believe 1+
Explanation:
when Na loses 1 electron in the outer shell it has 8 valence protons on it's new most outer shell. so now it has 11 protons and 10 electrons. that extra proton (positively charged) adds one extra charge. so +1

Answer:
6.1 ×10^-19 J
Explanation:
From E= hc/λ
h= planks constant = 6.6×10^-34 Js
c= speed of light = 3×10^8 ms^1
λ= wavelength = 325 nm
E= 6.6 × 10^-34 × 3×10^8/325 × 10^-9
E= 0.061 × 10^ -17 J
E= 6.1 ×10^-19 J
The wavelength of the associated sound will increase.
