Which of the following is not true about s-block elements? AThey have large atomic sizes BThey have lower ioinisation enthalpies Cthey have variable oxidation state DThey form basic oxidesSubmit Which of the following isotopes of hydrogen is radioactive? A11H B21H C31H Dnone of these.Subm...
Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of ...
What type of researcher would use the other isotopes such as Uranium-238?Determine whether the following statement is true or false: Carbon-14 is an unstable isotope with a half-life of less than 10,000 years.A geologist dates the age of a volcanic rock using an iso...
Which of the following statements about electronic configurations of atoms and mononuclear ions, and atomic orbital quantum numbers, are true or false. a. The electronic configuration of Cu^+ is [ArHelium and lithium are two elements that differ on...
The industry is such that not only do insurance companies deny 51% of claims,they have enacted policies forbidding people from paying for the critical medication they need out of pocket, lest the insurance company lose control and revenue.“Either you pay us, or you pay no one,” is a lin...
STABLE isotopesGAUSSIAN mixture modelsCHEMICAL bondsRANKINGRationale Methods for multi‐isotope analyses are gaining in importance in anthropological, archaeological, and ecological studies. However, when material is limited (i.e., archaeological remains), it is obligatory to decide a priori which isotopic...
Inorganic additive, which is labeled by heavy and stable isotopes, where the labeling is firmly incorporated in the additive, is new. An independent claim is included for a method for the production of the inorganic additive.Eickschen, Ralf...
Which of the following is true about the electron configurations of the noble gases? 1. The highest occupied s and p sublevels are completely filled. 2. The highest occupied s and p sublevels are partially filled. 3. The electrons which the highest ene...
Stable hydrogen and oxygen isotopes provide a powerful technique for quantifying the proportion of root water uptake (RWU) from different potential water sources. Although many models coupled with stable isotopes have been developed to estimate plant water source apportionment, inter-comparisons of ...
