The valence electron of the light metals are all in the range of 1 to 3.
<h3>What are Valence electron ?</h3>
Valence Electron is the number of electrons in the outer shell of an atom which participate in bond formation.
Number of Valence Electron in Boron is 3 and other light metals lighter than Boron have 1 , 2 of Lithium and Beryllium respectively,
The valence electron of the light metals are all in the range of 1 to 3.

The answer is Oxygen ions & Chloride ions. Although<span> Dissolved Oxygen (DO) can not interact with the Lead, Orthophosphates have to be added continually or the barrier breaks down. If the barrier does break down, DO combines with Lead atoms, oxidizing them. It allows Lead to drain into drinking water. Once oxidized, Lead dissolves into the water instead of sticking to the pipe. </span>Flint’s water treatment plant did not add
orthophosphates, allowing the pipes to corrode, and Lead quickly contaminated the drinking water. Additionally, Flint River water had high levels of chlorides, which accelerate corrosion.<span>

Answer:
When salt is dissolved in water, the particles of salt get into the spaces between particles of water and starts dissolving and disappear.
Explanation:
Answer:
[Co(NH₃)₄(H₂O)₂]³⁺: coordination number = 6.
[Cr(EDTA)]⁻: coordination number = 6.
[Pt(NH₃)₄]²⁺: coordination number = 4.
Na[Au(Cl)₂]: coordination number = 2.
Explanation:
In this complex, Co is bonded with 4 molecules of NH₃ (with 4 coordinate bonds, one bond for each molecule) and 2 molecules of H₂O (with 2 coordinate bonds, one bond for each molecule) forming the complex with 6 coordinate bonds.
∴ coordination number = 6.
In this complex, Cr is bonded with 1 molecules of EDTA (with 6 coordinate bonds, 4 O atoms and 2 N atoms in EDTA molecule).
∴ coordination number = 6.
In this complex, Pt is bonded with 4 molecules of NH₃ (with 4 coordinate bonds, one bond for each molecule).
coordination number = 4.
In this complex, Au is bonded with 2 atoms of Cl (with 2 coordinate bonds, one bond for each atom).
coordination number = 2.
