The phrase "amounts of these elements" is correct and usable in written English.
It can be used when discussing quantities or measurements of specific elements in a scientific or analytical context.
Example: "The lab results indicated that the amounts of these elements were within the acceptable range for the experiment."
Alternatives: "quantities of these elements" or "levels of these elements".
Sulfur, with atomic number 16, and carbon, 6, are relatively abundant in meteoritic matter, and the presence of minor amounts of these elements in the core would effectively reduce the mean atomic number.
The relative amounts of these elements suggest the presence of white pigments such as white lead [15].
Natural zeolite also showed medium ability to absorb Fe and Cd from wastewater, so, high amounts of these elements are accumulated in the soil surrounding the pitcher.
Alternatively, if the slab components are liquid-like supercritical fluids or melts (Bureau and Keppler 1999; Hermann et al. 2006; Zheng et al. 2011; Kawamoto et al. 2012), such fluids could contain large amounts of these elements even without Cl (Kessel et al. 2005b).
As Russia Today notes, trace amounts of these elements give an important clue as to when the star formed relative to the Big Bang, thereby helping estimate its age.
Sizeable amounts of these elements were produced only in 1958 (Burris B. Cunningham and Stanley G. Thomson), and the first californium compound (0.3 µg of CfOCl) was obtained only in 1960 by B. B. Cunningham and J. C. Wallmann.
This is certainly true for uranium and thorium, because the amount of these elements in the crust is almost sufficient to account for the total amount of heat flowing out of the Earth.
But, the human body also contains trace amount of these elements, within certain ranges, which can be differentiated from their quantities.
Excessive amount of these elements, i.e., more than 300, 150 and 300 mg/kg can cause phytotoxicity in plants (Vitosh et al. 1994).
The human infecting lineage does contain a larger amount of these elements, possibly due to a loss of VIPER-related sequences in Tcm.
Images in the graphic condition contained more gory/bloody elements than those in any of the other two conditions; the images in the suffering condition contained a moderate amount of these elements; and images in the symbolic condition contained the least of these elements.
