Elements with isotopic atoms? An isotope is the same form of an element, but with a different number of neutrons. An element with isotopes/"isotopic atoms" is simply an element with isotopes.
Non-ionic and non-isotopic atoms (i.e normal, stable atoms) all have different numbers of protons and electrons.
Mono isotopic elements are stable isotope of an element.From 80 isotopic elements there are 26 radioactive elements discovered up till now.These mono isotopic may or may not be radioactive if they are radioactive they have halve lives.
Chemical elements are not mixtures (I do not think to the isotopic composition).
Isotopic labeling is used in the study of esterification to keep track of an atoms passage. This is done by a variation of a cell, a reaction, or a metabolic pathway. Isotopic labeling will find the quantitative analysis.
Because the differences in atoms make different elements. Elements are multiple of similar atoms.
Radiometric or isotopic dating.
Elements and compounds are both composed of atoms. Compounds are composed of two or more atoms of different elements.
Atoms are the basic units of elements.
All elements are composed of atoms.
They are related because atoms are made of matter,elements are made of atoms,and matter is made up of elements.

For elements with multiple natural isotopes the precise atomic mass could vary from place to place. Depending on the ratio of those isotopes. Living systems are a natural way isotopic concentration change in some elements. Lighter isotopes react faster and living systems will tend to concentrate them. Extraterrestrial sources of elements could have significantly different isotopic composition than Earth's. Nuclear decay could change some isotopes to different elements. Thus changing the isotopic ratios.
