How do you identify the type of a chemical reactions? How do valence electrons affect elements bonding with other elements? How do the nuclei of different isotopes of an element vary? How many different elements are in our bodies? How is an atom different from an element?
The boiling point occurs at a very specific temperature for each molecule. That is why it is often used to identify an unknown substance in qualitative chemistry. The reason that the boiling point is predictable is because it is controlled by thestrength of the bondsholding the atoms in the m...
Many formulas use Latin and Greek prefixes to identify the number of atoms or ions in the compound. Common prefixes include mono (one or single), bi or di (two or double), tri (three), tetra (four), penta (five), hexa (six) and hepta (seven). For example, carbon monoxide has one...
To determine the valence electrons in an atom, you write the electron configuration of the element in noble-gas-inner-core form. The electrons outside... See full answer below. Learn more about this topic: Valence Electron | Definition, Configuration & Examples ...
Compounds form when atoms chemically combine. When metals combine (react) with nonmetals, ionic compounds usually form. When nonmetals combine, covalent compounds usually form. Molecules are the smallest part of a compound that have the properties of the compound. Molecules have no charge, meaning...
Next, the C-O bond is polar covalent as the difference in electronegativities is 0.89. Now, you need to map the dipole moment to do the molecular geometry. One end of the molecule has a partial negative charge pointing out toward the oxygen. But this is also true on the other end. ...
How is a hydrogen bond different from a covalent bond? How can you identify metals and nonmetals on the periodic table? How are covalent bonds strongly linked? Describe a covalent bond. What are the properties of nonmetals? Why does metallic bonding only occur between metals?
'dashed' and 'wedged' bonds are used to represent covalent bonds projecting out of this plane, either away from or towards the viewer. - By the way, these are referred to as the "bonds" they represent rather than as 'lines' (in the diagram) because the symbol for a 'wedged bond' ...
Identify the polyatomic ions in the compound. Polyatomic ions are ionic molecules made up of more than one atom (often of more than one element). See References for lists of common polyatomic ions and their charges. Separate the cations and anions. Cations are ions with a positive charge; ...
An atom that has an equal number of protons and electrons is neither positive nor negative -- it has no net charge. If that atom gains or loses electrons, however, it may become a cation, an ion with a positive charge, or an anion, an ion with a negative
