The chemical nature of an element is determined (mainly) by the electronic configuration in the outermost shells. However, most elements have isotopes - atomic configurations that have the same outer shells, but which may have a different number of neutrons in the atom core. This gives them the same chemical nature, but a different mass. Many isotopes are unstable in the long run - they will spontaneously disintegrate.

Are the symbols of elements different in different countries?
no
What is responsible fot the differences in people?
DNA is responsible for the differences in people.

Atoms of different elements can " stick together " ( making compounds ) via elements sharing or trading arrangements called
What accounts for the variation Darwin observed among island species?
Based on the study by Abzhanov et al. (Bmp4 and Morphological Variation of Beaks in Darwin's Finches. Science 2004 ), the differences in beak shape is partly determined by the expression of a signaling factor (Bmp4). Finches that have larger and broader beaks were shown to express Bmp4 earlier in development and at higher levels. Finches with different shaped beaks were able to exploit different food sources and this allowed the many beak shapes to remain present. After hundreds (or thousands) of years, the birds diverged and became different species.
How are atoms and elements different?
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle
Why is it important to understand the differences among different types of health plans?
wht is it important to undrestand the differences among different types of health plans
Why are atoms and elements alike?
Because the differences in atoms make different elements. Elements are multiple of similar atoms.
What are the differences between the elements?
Each element has an atom that has different amounts of protons, neutrons, and electrons. This is the case for the element's atomic number and atomic mass. They are arranged by their differences on the periodic table of the elements. Most elements are metals. The three categories for the elements are metals, nonmetals and metalloids. ----
Are isotopes different in terms of their chemical properties?
A difference of chemical properties is observed for light elements; for other elements these differences are extremely small.
The differences among the three categories of cytoskeleton elements would suggest that each what has specialized roles which is the correct match?
microtubules and chromosome movement
What are the objectives for compare and contrast lessons?
Students need to be able to look at two objects or elements in text and be able to describe the similarities and differences among them.
How do variations in this structure account for functional differences among membranes?
Different membranes have different scatters of proteins that are located in with the phospholipid bilayer. These different proteins have different functions.
What are two ways in which atoms of different elements are different from one another?
They have different numbers of electrons, protons and neutrons. These small differences can change the element dramatically.
Explain the differences among the three kinds of maps?
there are different kinds of maps such as physical maps and political maps
Is an element a new substance or does it even change state?
I'll try to answer what I think you were trying to ask.Different elements are different substances. Technically, different isotopes are different substances as well, but in practice the chemical differences between two isotopes of the same material are much smaller than the differences between two different elements.All elements (and nearly all compounds) undergo state changes.
Can two walk unless they agree?
Of course they can. They can choose to respect differences among people, or they can choose to walk in different directions.
