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...
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 ...

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 ...
What is the electron configuration for an atom in an excited state? How can one balance chemical equations with given oxidation numbers? If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of prot...
Is it purely from memorization??? Could you give me other examples where transition metals only have one oxidation state? Thank you !!! all help appreciated
Instead of having to draw a driver's blood to test his alcohol level, an officer can test the driver's breath on the spot and instantly know if there is a reason to arrest the driver. Breathalyzers operate so well because they understand how the body processes alcohol. How Much Alcohol ...
In its pure form is a reddish-brown metallic element with the ability to assume various oxidation states, namely +2, the most abundant and stable oxidant state. Copper is obtained from ores and later is usually subject to roasting, converting, and electrolytic refining [56]. Metal copper ...
Curcumin has raised interest as an agent of potential use in therapy of RA with the regulatory function of the related inflammatory factors associated with anti-oxidation [98]. Curcumin treatment activated caspase-3 and -9, up-regulated Bax, down-regulated Bcl-2 and Bcl-xL, and degraded poly...
