What do all atoms have the same element have in common?
All atoms of the same element have the same number of protons in the nucleus and consequently have the same atomic number. Atoms of an element usually have the same number of neutrons as protons. Atoms of the same element that have a different number of neutrons are called isotopes.
What are the similarities between elements and atoms?
Elements are composed of only 1 type of atoms and any subdivision can only result in same element. All the atoms of an element have the same properties (assuming they are the same isotope). Some examples are iron, magnesium, gold, etc. Compounds are composed of two or more elements in a fixed ratio.
What are the similarities of element?
On first glance, elements and compounds might appear different, yet they share many similarities, like being made up of atoms and having bonds linking their atoms together. Elements and compounds also share the qualities of being both pure and homogeneous substances.
What are the similarities and differences between elements and compounds?
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule.
What do all atoms of the same element have in common?
Isotopes have the same atomic number but different atomic masses.Atoms of an element share that element’s chemical and physical properties, such as boiling point, melting point and stability.An element is the simplest form of matter and cannot be broken down further by chemical means.
What makes an isotope of an element the same?
(iii) And if it is the same isotope, each nucleus contains the same number of neutrons, where the neutron is a massive, fundamental particle of zero charge. The number of protons and neutrons gives the identity of the isotope.
How many elements are there in the periodic table?
There are 118 known elements, arranged in the periodic table in order of atomic number. Of these elements, only the first 98 are naturally occurring. The other elements have been produced artificially or as a result of nuclear reactions.
What do all the isotopes of hydrogen have in common?
Explanation: (iii) And if it is the same isotope, each nucleus contains the same number of neutrons, where the neutron is a massive, fundamental particle of zero charge. The number of protons and neutrons gives the identity of the isotope. There are three common isotopes of hydrogen: protium,1H;deuterium,2H, and tritium,3H.
