If a silicon atom has four valence electrons, what is the maximum number of bonds it can form? What is the best way to balance the chemical equation Fe(HCO_3)_3 + CaO rightarrow Fe_2O_3 + Ca(HCO_3)_2? How many sides do tetrahedral dice have? How can one balance chemical equati...
40K Covalent bonding is when atoms share one or more electrons, and electrons orbit the nucleus of an atom in shells. Explore how electrons create energy shells, what the octet rule is, the relationship between atoms, and covalent bonds and compounds. Related...
In the Lewis formula for {eq}ClF_3{/eq}, how many lone pairs are around the central atom? Lewis Structure It is drawn from the molecular formula of the compound. This is otherwise called an electron-dot structure, as electrons are shown as dots. This gives an idea abou...
Hydrogen shares its single valence electron with one of the valence electrons of oxygen; when two hydrogen atoms form these covalent bonds with a single oxygen atom, the result is H2O or water.(Image credit: Encyclopaedia Britannica/UIG Via Getty Images) Evolution of the Periodic Table When Men...
Many chemical elements of the periodic table can combine to form compounds. However, not all of the elements combine in the same way. It is important to take the individual properties of each element into account before writing the chemical compound that forms from combining them. The most comm...
In chemistry, metals and nonmetals form ionic bonds, and two or more nonmetals form covalent bonds. These two bond types represent fundamentally different atomic interactions: covalent bonds involve the sharing of electrons between atoms, whereas ionic bonds result from the atoms possessing opposite ...
(Carbon, Silicon, Germanium) tend to form covalent bonds instead of forming 4+ ions. But still, 4 bonds, for group IVA. After that, we go the other direction -- Nitrogen -3, Oxygen -2, the halogens -1. And then the noble gases, which have a complete octet, and don't form ...
made of very large molecules. Examples of naturally occurring polymers include quartz and other common minerals, while synthetic polymers include nylon and polyester. Silicone is another synthetic polymer, and its main ingredients are silicon and oxygen, which are joined together bycovalent bonds. ...
