The ground state of an atom is when the atom has an equal number of protons and electrons. When this happens, the atom is said to be electrically neutral. Electrons are arranged in an atom in different orbitals. Each orbital differs from the...
If Argon is a noble gas and its atomic number is 18, how many electrons can be found in the valence level? Show work How abundant is einsteinium? Why are noble gases chemically inert? How reactive is tennessine? What are the differences between Argon, Neon, O2, and H2O when heated from...
An atom that has an equal number of protons and electrons is neither positive nor negative — it has no net charge. If that atom gains or loses electrons, however, it may become a cation, an ion with a positive charge, or an anion, an ion with a negative charge. Chemists use a very...
This simple atom consists of a nucleus (containing the protons and neutrons) and an electron cloud. It's helpful to think of the electrons in this cloud circling the nucleus in many different orbits. Absorbing Energy Absorption of energy: An atom absorbs energy in the form of heat, light ...
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...
parts: a power source and an accelerating tunnel. If a functional particle beam weapon could be built, it would use its power source to accelerate electrons, protons or hydrogen atoms through the tunnel, which would focus these charged particles into a beam that would be fired at the target....
Ions: Positive and Negative Atoms have no electric charge, because they maintain an equal number of protons (positively charged subatomic particles) and electrons, subatomic particles with a negative charge. In certain situations, however, the atom may lose or gain one or more electrons and acquire...

valence electrons (VE)theneutralatom has (e.g. 3 for boron, 4 for carbon, 5 for nitrogen, and so on).(note: this is also equivalent to the effective nuclear charge Zeff, the number of protons that an electron in the valence orbital “sees” due to screening by inner-shell electrons....
