yes, but noble gases no
The smallest part of an element that can take part in a chemical reaction is an atom. Atoms are composed of protons, neutrons, and electrons, and they are the building blocks of all matter in the universe.
An atom. However it should be noted that generally the valence electrons in an atom take part in a chemical reaction.
The electrons
The nucleus of an atom is the part that takes part in nuclear reactions. It consists of protons and neutrons, which are involved in processes such as fission and fusion. The electrons surrounding the nucleus are not typically involved in nuclear reactions.
The valence electrons are the part that takes place in a chemical reaction.
Only the valence electrons
Electrons.
the valence electrons
In atom's centre its Nucleus present which is consist of two parts protons and neutrons, in a chemical reaction nucleus doesn't take part, only electrons take part, when there is a change in nucleus, its due to "Fission" or "Fusion" reaction, Atomic blast and the electricity producing from nuclear energy perform the same reactions.
Electrons - the valence electrons
No. An atom is made of Elements. Name of element is decided by number of Protons, containing in it's Nucleus. Two or more different types of elements react with each other to form compound in what is called as chemical reaction.
Not fusion, but a fission reaction.
