There are three isotopes possible with mass number 65: Ni-65, Cu-65 and Zn-65. Only one of them:Cu-65 is occurring naturally (30.9%) with mass 64.92779 a.m.u.It is not a very accurate and reliable method to identify isotopes by mass. Atomic number or other properties of that element are more trustful.
No, the least reliable indicator of a chemical change is shape. Change of shape usually indicates a physical change, unless the material change resulted from a recombination or decomposition of the material's chemical form, as in the rotting of vegetable matter.
Mineralogists often use the physical properties of minerals to identify them. The most reliable test in order to identify a mineral is the test for hardness.
HARDNESS
luster streak shape density color (not always reliable tho mulltiple types of minerals can have the same color) odor tenacity reaction to acid cleavage magnetism electrical properties
what is the most reliable way to identify a mineral?
color yo
color!!
i think softness and hardness
A reliable protocol is one that ensures reliability properties with respect to the delivery of data to the intended recipients
unreliable sources show nothing close to many reliable sources
