Question

.Write the electron dot structures of the following molecules: - Hydrogen - Nitrogen - Water - Carbon dioxide - Ammonia ​

Answer 1

CO2

lithium 1 s 2 2 s 1 1 valence electron

beryllium 1 s 2 2 s 2 2 valence electrons

nitrogen 1 s 2 2 s 2 2 p 3 5 valence electrons

neon 1 s 2 2 s 2 2 p 6 8 valence electrons

Assertion: Ammonia shows a trigonal pyramidal molecular structure. Reason: In the structure of ammonia, three atoms are attached to the central atom and thus, shows tetrahedral electron pair geometr

The structures of molecules that are held together by covalent bonds can be diagrammed by Lewis electron-dot structures. The hydrogen molecule is shown in the figure below. The shared pair of electrons is shown as two dots inWhat would be the electron dot structure of carbon dioxide which has the formula CO2? SOLUTION: Ans.: The atomic number (Z) for carbon is six and its electronic configuration is 2, 4. Carbon has four valence electrons. Each oxygen atom (Z = 8) has six valence electrons (2, 6). between the two H symbols (H:H)
