Question

How to draw the electron dot structure of H2O, NH3 and CH4?

Answer 1

So here are ur answers of H2O and NH3 .. do it similarly in case of CH4 (C HAS 4 ELECTRONS IN THE OUTER ORBIT )

Answer 2

Electronic Dot Structure:

Explanation:

• Since, every atom of an element needs  to be stable. The term stable  it mean that atom will not be excited to react further. If we want to achieve this state, wld follow electronic dot structure . So, an atom can either lose electrons or be  may gain electrons to achieve that  order.
• Generally, metals and non-metals have the property to lose and gain electrons .
• Atom of all elements complete 8 electrons with  its outermost shell to get stable .
• Hydrogen is an such  element which gets stable on having 2 electrons  its outermost shell.
• In  water molecule, 1 oxygen atom and 1 hydrogen atom  6 electrons and 1 electron in their outermost shell . So, one oxygen atom shares 1 electron each with two atoms of hydrogen.
• Similarly, 1 nitrogen have  5 electrons in its outermost shell. thus, 1 nitrogen  shares its 1 electron each  3 atoms of hydrogen.
• Now, 1 carbon atom have  4 electrons in its outermost shell. So, 1 carbon atom shares 1 electron  with 4 atoms of hydrogen.
