The periodic table is organized in a way in which trends with certain things such as ionization energy or atomic radius would "work out". It also have increasing atomic mass.
It's also organized to tell you the electron and proton of each element, least to greatest. (the atomic number) Example: Chlorine has 17 protons and 17 e-
(Left to right)
(Top to bottom)
Lanthanum and actinium play the role of being in the bottom because of their large atomic radius and having many protons/electrons.
They're also in the F block for electron configuration.
Answer:
28.82°
Explanation:
the equation for a diffraction grating is given by
where d is the distance between slits, m is the order of the bright fringe and lambda is the wavelength of the light. By replacing we obtain:
Then, for the third fringe the angle is 28.82°.
hope this helps!!
<span>Light waves travels through electromagnetic radiation
when we switch on the lamp, vibrations of electric and magnetic fields will release energy to its surrounding environment. Which the reason why the area around the lamp will feel warmer when we light it up.</span>
