What type of reaction happens in a nuclear power plant?
Zanzabum
When a large fissile atomic nucleus such as uranium-235 or plutonium-239 absorbs a neutron, it may undergo nuclear fission. The heavy nucleus splits into two or more lighter nuclei, (the fission products), releasing kinetic energy, gamma radiation, and freeneutrons

Use condensed electron configurations and Lewis electron-dot symbols to depict the ions formed from each of the following atoms,
Dennis_Churaev [7]

The formula for Cs and S is Cs₂S.

For Cs and S,

Ions formed will be Cs⁺ and S²⁻

As cesium belongs to group 1A and sulfur belongs to group 6A. Therefore, the condensed electronic configuration is -

For Cs is [Xe} 6s¹ and for S is [Ne] 3s²3p⁴.

Cs have 1 valence electron and S have 6 valence electrons.

Hence to attain a stable electronic configuration, both two Cs atoms lose one electron and form Cs⁺ and these two electrons will be accepted by one S atom to form S²⁻.

Therefore the formula for the compound is Cs₂S as Cs donate 1 electron and S will accept 2 electrons from Cs.

The formula is Cs₂S.
