Negative ions that consist of a single atom are named by adding the suffix -ide to the stem of the name of the element. What metals form negative ions? Ions -- electrically charged atoms -- can carry a positive or negative charge. Positive ions are cations and are typically metals like ...
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. Can an atom have ...
In ionic bonding, why are atoms losing an electron forms positive ions but not negative ions, and similarly atoms gains an electron to form negative ions but not positive ions? Why do halogens have high electron affinity? Why do ions conduct electricity?
Why do elements form compounds? Why does having a high electronegativity signify being more reactive? Why do atoms hybridize? Why can't molecules with the following formulas exist? (a) CH5 (b) C2H6N (c) C3H5Br2 Why should samples be weighed rather than measured volumetrically when dete...
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 ...
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.
The ionic radii of the ions S2-, Cl-, and K+ are 184, 181, 138 pm respectively. Explain why these ions have different sizes even though they contain the same number of electrons. Unlike elements in groups 1A-3A, which can form cations, and atoms ...
<p>To understand why nitrogen exhibits anomalous behavior compared to other members of its group (Group 15 of the periodic table), we can break down the explanation into several key points:</p><p>1. <strong>Small Size</strong>: - Nitrogen is the smal
Why do nonmetals tend to form negative ions? Why don't two neutral charges react? In ionic bonding, why are atoms losing an electron forms positive ions but not negative ions, and similarly atoms gains an electron to form negative ions but ...
If atoms exist, why can't we see them with visible light? Explain why the energy level of an atom become energy bands in a solid. Why is a rainbow curved? Why will a magnet attract an ordinary nail or paper clips but not a wooden pencil?
