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.
What else can I help you with?
Atoms of different elements are what?
Atoms of different elements have no specific relationship but if they have same no of neutrons then they are isotones, if they have same mass no then they are isobars, atomic no of two elements can neither be same.
What isotopes are atoms of the same elements with different number of?
Isotopes are atoms of the same elements with different number of neutrons.
What fats are made of the same elements but in different proportions?
Fats are made of the same elements as carbohydrates, but in different proportions.
How are elements determind?
Elelments are determined by the amount of protons they have. While different elements can have the same number of neutrons and protons, no two different elements can have the same amount of protons.
Why the mass number of the same atom of an element is not constant?
Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.
Which characteristics of an atom always varies among atoms of different elements?
The number of protons is always different. Depending on isotopes, the number of neutrons and atomic mass can be the same as another element. Electrons almost always are varying in number, making elemental ions have the same number of them.
How can two coumpounds made from the same element be so different?
Because the proportions of the elements are different in the different compounds. They may contain the same elements, but the different proportions make them different compounds with different properties.
What are the difference among the same elements?
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.
Why do elements within a period of the periodic table have different properties?
They have different numbers of valance electrons...
No two different elements will have the?
No two different elements will have the exact same atomic number. Each element has a unique number of protons in its nucleus, which determines its atomic number and distinguishes it from other elements.
Do Elements in a group have the same number of neutrons?
No, none of two elements in any group have the same number of neutrons. But there are such elements across a period, and they are known as isotones. Some examples are; carbon-12 and nitrogen-13 oxygen-18 and fluorine-19 phosphorus-31 and sulfur-32
Why elements of the same shape have different boiling points?
elements of same shape have different boiling points because their bonding may vary! the elements with covalent bonds will have high boiling point!
