All Atoms Of The Same Element Have The Same. Isotopes have the same atomic number but different atomic masses. What is the hypothesis that les to the discovery of the proton.
This model of the nucleus requires the introduction of a force other than those discussed earlier, one that will allow the protons, with their mutually repelling positive charges. Isotopes have the same atomic number but different atomic masses. An element is the simplest form of matter and cannot be broken down further by chemical means.
For example, the element hydrogen has atoms that have one proton in the nucleus.
Generally, isotopes behave the same way during chemical reactions. All atoms of the same element have the same atomic number. The atomic number is equal to the number of protons in an element.
Why did jj thompson reason that electrons must be apart of the atoms of all.
Every atom of a particular element has the same number of protons. Then the different atoms of the same element differ in their protons. An element is a substance consisting of atoms that can no longer broken down into other substances, which all have the same number of protons, which translates into its atomic number.
The best known is oxygen (O). The extra neutrons just change the mass of the atom and its density. Different isotopes of the same element can have different mass numbers, so A is wrong.
Atoms of the same element (a.k.a. isotopes) have different mass numbers.
Generally, isotopes behave the same way during chemical reactions. Atoms of an element share that element's chemical and physical properties, such as boiling point, melting point and stability. An element is a substance that is made entirely from one type of atom.
For instance, one isotope of oxygen has eight protons and eight. Note that they are still the same element, as the atomic (proton) number is responsible on what element is currently there. Some atoms can form covalent bonds with other atoms of the same element to form diatomic molecules.
The atoms of a chemical element can exist in different types. Different isotopes of the same element have different masses. Atoms of a particular element must have the same number of protons but can have different numbers of neutrons.
