2. F is non-metal, because it has seven electrons (more that 3)
3.It <span>fills its shell by gaining one electron, because it is easier to gain 1 e⁻ than to loose 7 e⁻.
4. It </span><span>becomes a negatively charged ion, because atom of F is neutral, it has "0" charge, and it takes one negatively charged electron(-1). (0 +(-1)= -1)</span>
Answer:
Low energy waves have <u>a long wavelength.</u>
Explanation:
Energy of wave is directly related to the frequency while it is inversely proportional to the wavelength.
If any wave have high energy it will have high frequency and smaller wavelength.
If the wave have lower energy then it will have lower frequency and higher wavelength.
Mathematical relationship:
E = h. f
E = h. c/λ
E= energy
h = planck's constant
f = frequency
c = speed of light
λ = wavelength
Answer:
The key difference between empirical and molecular formulas is that an empirical formula only gives the simplest ratio of atom whereas a molecular formula gives the exact number of each atom in a molecule.
Could you attach a picture because I can tell you didn't post the entire question.
