An atom of nitrogen has 7 protons and 7 neutrons. Heavy elements have a large number of protons and neutrons. For example, the most common isotope of uranium, uranium-238 has 92 protons and 146 neutrons in its nucleus. The drawing on the left shows a carbon atom with 6 protons, 6 ...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that e...
What is a helium-4 atom with no electron? What are the two parts of an atom? What makes one atom different from another? How many protons are in an atom of copernicium? What is the history of an atom? What is the mass number of an atom with 5 protons and 7 ...
The atomic number of oxygen is 8. What is the mass number of a oxygen atom with 7 neutrons? Compare the differences between gram and atomic mass unit (amu). What is the atomic number of carbon-12? What is the mass number of an atom with 5 protons and 7 neutrons?
The interactions of neutrons with nuclei had been studied during the mid-1930s by Italian-born American physicistEnrico Fermiand others. Nuclei readilycaptureneutrons, which, unlike protons or alpha particles, are not repelled from the nucleus by a positivecharge. When a neutron is captured, the...
Describe the structure of an atom.An atom consists of a nucleus, which contains protons and neutrons, surrounded by electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The number of protons determines
Atomic Particles Atoms are made of protons, neutrons and electrons 99.999999999999% of the atom is empty space Electrons have locations desc
The atomic weight of an atom is given in most cases by the mass number of the atom, equal to the total number of protons and neutrons combined. An atom may be conveniently symbolized by its chemical symbol with the atomic number and mass number written as subscript and superscript, ...

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...
