Selma is creating a visual representation of the sun and its components for her science fair.
Brilliant_brown [7]

Radiative zone is missing from the three sections of the sun's interior in the diagram.

<h3>What is the Sun's radiative zone?</h3>

A radiation belt. The radiative zone is a layer of dense, highly ionized gases that is constantly being bombarded by gamma rays from the core. It contains 24% helium and 75% hydrogen. Most of the atoms in this region are electron-deficient, so they are unable to absorb photons for convection to the surface.

<h3>What importance is the radiative zone of the Sun?</h3>

The Sun's radiative zone sits in between the convection zone and the core. The convection zone receives radiation from the core's high energy nuclear explosions and the plasma they produce. The radiative zone is where the sun's flares and CMEs originate.

Electrons spin in shells around the nucleus. The closest shell (n = 1) can contain a maximum of _____ electrons?
LUCKY_DIMON [66]

The given blank can be filled with two electrons.  

The K, L, M, N are the four shells in an atom. The K shell is the initial that is present nearest to the nucleus of the atom, and it comprises two electrons. The L shell can withstand eight electrons, M shell can withstand eighteen electrons, and however, the atom attains stability if the last (valence) shell comprises eight electrons.
