show with the help of diagram of electronic configuration how the following compounds are formed from the constituent atom.
1. potassium chloride
2. water
3. HCL
Answers
Answer:1. Sodium Chloride:
Sodium chloride is formed when sodium atoms comes in contact with chlorine atoms. When both the atoms interact the sodium loses one electron to chlorine. This makes sodium positively and chlorine negatively charged. Since opposite charge attracts each other, the sodium atom attracts chloride ions thus forming an ionic bond. The chemical formula for sodium chloride is NaCl.
2. Potassium Fluoride
The chemical formula of potassium fluoride is KF. Potassium fluoride is formed by dissolving potassium carbonate in excess hydrofluoric acid. Evaporation of the solution yields potassium bifluoride. The bifluoride on heating gives potassium fluoride:
K2CO3 + 4HF → 2KHF2 + CO2↑ + H2O
KHF2 → KF + HF↑
3. Water
The chemical equation of the formation of water is
2H2 + O2 = 2H2O
Two molecules of diatomic hydrogen gas combined with one molecule of the diatomic oxygen to produce two molecules of water.
4. Hydrogen Chloride
Hydrogen chloride is produced by treating sodium chloride with concentrated sulphuric acid.
420K
NaCl + H2SO4 → NaHSO4 + HCl

potassium chloride:- When we write the configuration we'll put all 19 electrons in orbitals around the nucleus of the Potassium atom. In writing the electron configuration for Potassium the first two electrons will go in the 1s orbital. ... Therefore the Potassium electron configuration will be 1s22s22p63s23p64s1.
water :- Water has four core electrons and four valence electrons for its oxygen (1s2, 2s2, 2p4, basically 4 's'-state and 4 'p'-state) and its hydrogen atoms share electrons with the oxygen's outer orbit. Hydrogen's configuration is '1s1'.
HCL:- Composite image of the atomic and electronic structure of the molecule hydrogen chloride. This diatomic molecule consists of a hydrogen atom (H, left) forming a single covalent bond with a chlorine atom (Cl, right). ... This fills the outer electron shell, forming a strong and stable bond.
