Atoms become imbalanced by the loss or gain of atoms. When atoms loose these electrons, they are positively charged; when they gain electrons they are negatively charged. Once an atom stops being considered a neutral atom by either becoming a positive or negative atom, this creates static electr...
Does a Lewis structure tell which electrons come from which atoms? Explain. If you draw Lewis structures of an ion, what do you do with the electron count for an anion? What do you do with the electron count for a cation? The number of valence electrons (...
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 charge. Chemists use a very...
Why does Lewis Structure for BeF_2 have 2 bonds instead of 4? A neutral oxygen atom will form how many bonds and have how many lone pairs? What is the Lewis structure of the covalent compound that contains one nitrogen atom, one hydrogen atom, and one carbon atom? For the molecule ...
(SIADH), which remains in essence, a diagnosis of exclusion. Nevertheless, other biological features may represent a valuable aid for physicians investigating the presence of SIADH. They include lowered plasma uric acid and blood urea nitrogen, and failure to correct PNa levels following the in...
These dipoles can interact with each other in anattractivefashion, which will alsoincreasethe boiling point. However since the electronegativity difference between carbon (electronegativity = 2.5) and the electronegative atom (such as oxygen or nitrogen) issmallerthan it is for hydrogen (electronegativity...

-2 . polyatomic ion nh4+ or ammonium most polyatomic ions contain oxygen and are negatively charged anions because the oxygen atoms attract electrons. ammonium is one of the few positively charged polyatomic ions or cations and doesn't contain oxygen. nitrogen has five electrons in its outermost ...
The nitrogen atom is the central atom and the hydr How many bonds can each atom make without hybridization? Mg 3s_2 Which of the following molecules have the same hybridization of the central atom?: A) BeCl2 and H2O B) NH3 and PCl5 C) BCl3 and CO2 ...
One possibility is the synthesis of nitrogen-linked O-phospho-L-serine (OPLS) analogs, of which, there are a number of synthesis the methods, one of which involves the dissolution of succinic acid (10 mmol) in water (20 ml) and cooled either by refrigerator or, say, in an ice bath to...
