Because an ordinary atom has the same number of electrons as protons, an element’s atomic number also tells how many electrons its atoms have, and it is the number and arrangement of the electrons in their orbiting shells that determines how one atom interacts with another. The key shell ...
1. the smallest component of an element having the chemical properties of the element, consisting of a positively charged nucleus of neutrons and protons that exerts an electrical attraction on one or more electrons in motion around it. 2. this component as the source of nuclear energy. 3....
ATOMIC NUMBER equals the number of protons (positively charged particles) in an atom's nucleus, or center. Name that element! Such deterministic control of single atoms has a wide range of potential applications, including quantum information processing, atom-by-atom nano-technology, and fundamental...
The number of protons in a particular nucleus, i.e. the atomic number of the atom, is equal to the number of electrons in a neutral (nonionized) atom. The arrangement and behaviour of these electrons determine the interactions of the atom with other atoms and thus govern chemical properties...
The atomic nucleus is the core of an atom and is made of protons and usually, another subatomic particle called neutrons. The number of protons in an atom is called the atomic number. The atomic number defines an atom as a specific element. For example, atoms with the atomic number 6 ...
An atom is composed of three particles, namely,neutrons, protons and electronswith hydrogen as an exception without neutrons. Every atom has a nucleus that bounds one or more electrons around it. The nucleus has typically a similar number of protons and neutrons which are together known as nucle...
Atom - Mass, Isotopes, Structure: The number of neutrons in a nucleus affects the mass of the atom but not its chemical properties. Thus, a nucleus with six protons and six neutrons will have the same chemical properties as a nucleus with six protons and
In the presence of heavier elements, particularly carbon and nitrogen, a catalytic sequence of nuclear reactions aids the fusion of protons to helium (H. A. Bethe and C. F. von Weizsäcker, 1938) (Fig. 1.4). The overall reaction is precisely as before with the evolution of 26.72 MeV,...

If the atomic weight is 4.001, you can be confident the atom is helium, with 2 protons and 2 neutrons. An atomic weight closer to 5 is more troublesome. Is it lithium, with 3 protons and 2 neutrons? Is it beryllium with 4 protons and 1 neutron? If you're not told the element name...
