When we are done adding valence electrons we check each atom to see if it has an octet (full outer shell). We also need to check to make sure we only used the number of available valence electrons we calculated earlier. There are 8 valence electrons for the H3O+ Lewis structure. Carbon dioxide is a covalent compound comprised of three atoms, carbon surrounded by two oxygens. Both carbon and oxygen contain p orbitals that are able to interact based on symmetry compatability. Valence bond (VB) theory predicts four bonds for carbon and two for each oxygen. The bond order of each carbon-oxygen bond is 2.
Calcium Phosphate is Ca 3 (PO 4) 2 because Ca's valency is +2 and PO 4 's valency is -3.So three times +2 and two times -3 make +6 and -6 respectively which cancel out. Now Carbonate is unstable because CO 3 has 3 atoms of oxygen which makes the valency -6 but C has only +4 so it is unstable. The atom have 3 valence electrons in its valence shell. Explanation: Electronic Configuration of give atom is, 1s², 2s², 2p⁶, 3s², 3p¹ As the this atom has three energy levels, i. e. 1, 2 and 3 so the valence energy level or Shell is three. In third shell two electrons are present in s orbital and one electron is present in p orbital.

Dec 03, 2020 · There are a number of steps involved in photosynthesis, but it basically involves the transfer of electrons from water (H 2 O) to carbon dioxide (CO 2), freeing oxygen (O 2) from the carbon dioxide, which allows the water to combine with carbon to make glucose (C 6 H 12 O 6) — the simplest carbohydrate. Consider carbon dioxide (CO 2). If each oxygen atom shares one electron with the carbon atom, we get the following: This does not give either the carbon or oxygen atoms a complete octet; The carbon atom only has six electrons in its valence shell and each oxygen atom only has seven electrons in its valence shell.
