In contrast, the oxidation number is the number of electrons an atom can donate or accept to form a bond with another atom. Q.2. Why do d-block elements have a variable oxidation state? Ans. The d-block or translational elements have incomplete d- and s-subshells. The valence electrons...

they’re substances that help prevent oxidation. This proper balancing of free radicals and antioxidants is a vital bodily function. Without it, the body can be in a state of oxidative stress too often or for too long, which can be damaging ...
How can one find the valency of an element? How do cations and anions gain or lose protons and electrons? How do you show the number of protons and neutrons on a Bohr-Rutherford diagram? Explain valance electrons What is the electron configuration for an a...
My son, for example, has a glow-in-the-dark yo-yo, a glow-in-the-dark ball, a glow-in-the-dark mobile and even (if you can believe it) a pair of glow-in-the-dark pajamas! They make him easy to find at night! If you have ever seen any of these products, you know that ...
Using the formula: Eq = MW / n • Eq = equivalent weight • MW = atomic or molecular weight in g/mol, from periodic table • n = no. of equivalents For H3PO4: • Eq = unknown • MW = 127 g/mol. Look at a periodic chart and find the the atomic masses of the H, ...
Re: How the heck do you know the... «Reply #1 on:January 29, 2008, 06:03:21 PM » This depends on if you know the difference between oxidation state and charge. also as you learn more about transition elements it will become clear to you why you shouldn't memorize things but ...
A driver might be found to have a level of 0.15, for example, while the legal limit is 0.08. To comprehend how we can gain access to such precise numbers, we have to ask ourselves: how does a breathalyzer work? What do those figures mean? And how do police officers find out if ...
If you want to see a hologram, you don't have to look much farther than your wallet. There are holograms on most driver's licenses, ID cards and credit cards. If you're not old enough to drive or use credit, you can still find holograms around your home. They're part of...
The different results achieved by each class can be explained either by the mechanism of action of the included actives for the concentrations of their use. Although this last information is not available it is expected to find a higher concentration of actives in medicines than in cosmetics. In...
