Draw the electron-dot structure for chclo. draw the molecule by placing the atoms on the grid and connecting them with bonds. include all lone pairs of electrons.

Answer :

Electron-dot structure : It is also known as Lewis-dot structure. It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.  The valence electrons are represented by 'dot'.

The given molecule is,

As we know that carbon has '4' valence electrons, hydrogen has '1' valence electron, chlorine has '7' valence electrons and oxygen has '6' valence electrons.

Therefore, the total number of valence electrons in, = 4 + 1 + 7 + 6 = 18

According to electron-dot structure, there are 8 number of bonding electrons and 10 number of non-bonding electrons.

The electron-dot structure of is shown below.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
