The conditions given in the question describe a molecule of either acetone or propionaldehyde. In either instance, 6 hydrogen atoms are required to complete the molecule: H3C-C(O)-CH3 or H3C-CH2-CHO.
Carbon = 4 valance electronsNitrogen = 5 valance electrons4 + 5 = 9 and 2 valance electrons used for the single bond, 9 - 2 = 73 hydrogens can attach to the carbon and 4 hydrogens can attach to the nitrogen, so.......7 hydrogen atoms would complete this molecule===================================
Glucose is formed using Covalent Bonding. This is proven because none of the elements that form Glucose are metals (Carbon is a Gas, Hydrogen is a Gas and Oxygen is a Gas). Ionic Bonding is the transfer of elections from METAL to NON-METAL. If you are drawing a diagram of the Glucose (to show how many electrons are shared with each element), simply draw a ring of the Carbons. Then, draw 1 Hydrogen connected to the Carbons, by themselves. Finally, draw an Oxygen connected to each of the Carbons, with a further Hydrogen connected to each of the Oxygens. Now, with Glucose, you have 12 Hydrogens that all need another Electron to complete it's outmost shell. Hydrogen, only having 1 proton (therefore having 1 electron), needs just one because the stable form of electrons is always 2,8,8. Hydrogen is also in Group 1, so it only has 1 shell. The 6 Hydrogens connected directly to the Carbons will share it's only electron with the Carbon. The Carbon, in turn, will share 1 electron back, leaving the Carbon with 3 electrons that it can share and it will also need 3 more electrons to complete it's outer shell. The 6 Hydrogens connected to the Oxygens will also share it's only electron with the Oxygen. The Oxygen will also share 1 electron with the Hydrogen. At this stage, the Hydrogens will all have a complete outer shell. Now, the Oxygen needs 1 electron to complete it's outer shell and the Carbon needs 3 to complete it's outer shell. So, simply share 3 electrons from each Oxygen with the Carbon and allow the Carbon to share a single electron. You will find that every atom has a full outer shell. It does get a bit confusing, I know. But you've just got to remember that Ionic Bonding is the TRANSFER of Electrons from METAL to NON-METAL. If a Metal is not present, it is not Ionic Bonding.
yes, because it is combination between 2 nonmetals
When two hydrogens bond, they share their electrons. This makes it covalent. I think this is what you were asking.
This compound makes a double covalent bond between nitrogen and oxygen.

This compound makes a double covalent bond between nitrogen and oxygen.
Silicon dioxide has a network covalent bonding.
As carbon and hydrogen are both nonmetals, it is covalent.
Covalent
Atoms connected by covalent bonds share pairs of electrons to achieve a stable electron configuration. These shared electrons are localized between the bonded atoms. Additionally, covalent bonds are formed by the overlap of atomic orbitals.
Covalent because it is between 2 nonmetals and it could also be a polar covalent
