Atoms form chemical bonds to make their outer electron shells more stable. The type of chemical bond maximizes the stability of the atoms that form it. An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons an...
Why does carbon form covalent bonds? Explain how you determine the number of electrons that will go on the valence shell of an atom. Why do atoms form bonds? How to determine valence electrons? Why do ions form covalent bonds (polyatomic ions) if they already have complete valence shells du...
Why does atomic radius increase down the group? Periodic Properties: The periodic table categorizes the elements according to their properties and atomic number (number of protons or electrons). Along the period (rows), the atomic number increases. Down the group (columns), chemical properties lik...
Why do ions form covalent bonds (polyatomic ions) if they already have complete valence shells due to their ionizing? Why do elements in the same group of the periodic table have similar properties? Why is the periodic table arranged the way it is?
The aurora borealis and aurora australis have dazzled us in the night sky for centuries. Here’s what causes them—and why we’re seeing them more lately.
The structures of pure metals are simple to describe since the atoms that form these metals can be thought of as identical perfect spheres. More specifically the metallic structure consists of 'aligned positive ions' (cations) in a "sea" of delocalized electrons. This means that the electrons ...
Why do nonmetals tend to form anions when they react to form compounds? Why can't the halide ions be oxidizing agents? Why do metals only form ionic compounds while metalloids and nonmetals form ionic and covalent compounds? Why are metals good conductors of electricity?
If you put a molecule of pure carbon dioxide together with hydrogen and oxygen atoms, you would soon find that these two would be attracted to each other due to their orbital radii around the nucleus of the carbon dioxide molecule.
Why don t atoms gain or lose protons?Atoms never gain protons; they become positively charge only by losing electrons. A positive ion is called a cation (pronounced: CAT-eye-on). You may have notice that the number of neutrons in each of these ions was not specified. ...
The ionization energy describes the energy required for this process for one mole of the gaseous atoms. The electron removed is at the highest energy, furthest from the nucleus. There are trends in the periodic table for ionization energy when you go across a period (row) or down a group ...
