Are isotopes are atoms of the same element? Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ
Are isotopes are atoms of the same element?
Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
How do you know if two isotopes are the same element?
all isotopes have the same number of protons and the same number of electrons. Because the electron structure is the same isotopes have the same chemical properties. What is different is the number of neutrons, The different number of neutrons all cause a difference in the atomic weight or mass of the atoms.
Can two atoms of two different elements be isotopes of each other?
Can two atoms with the same mass number ever be isotopes of each other? No- if they have the same mass number & different atomic numbers they are atoms of different elements. 17.
How are two atoms of the same element alike?
Atoms of the same element consist of the same atomic number that is number of protons or electrons and different mass number that is number of neutrons. This variation or change in the number of neutrons in an atom gives rise to different isotopes of an element. An element with different isotopes occurs in nature.
Are atoms in an element?
It can be easy to see why elements and atoms get confused because elements are atoms. They are just a group of all the same kind of atoms. All the known elements on Earth can be found in the periodic table of elements.
Which two atoms have the same mass?
Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Scientists define this amount of mass as one atomic mass unit (amu) or one Dalton. Although similar in mass, protons are positively charged, while neutrons have no charge.
Can two elements be exactly alike?
No. Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states.
Does an atom have a color?
atoms (as opposed to molecules) do not have colors – they are clear except under special conditions..
Why do atoms have different isotopes?
An isotope exists when there is a deficiency or excess of neutrons in an atom. The atoms in a certain element must have the same number of protons but may have different numbers of neutrons. This causes an element to have several isotopes which have similar chemical properties and behavior.
What are examples of isotopes and their uses?
Uses of Stable Isotopes. Scientists performing environmental and ecological experiments use stable isotopes of oxygen, hydrogen, sulfur, nitrogen and carbon. For example, in geochemistry , scientists study the chemical composition of geological materials such as minerals and rocks.
What are the different types of isotopes?
Scientists divide isotopes into two main types: radioactive and stable. Both types see wide use in several industries and fields of study. Stable isotopes help identify ancient rocks and minerals. Radioactive isotopes produce energy and serve in science, medicine and industry.
