How do you find the weight one atom? What is the difference between a molecule and an atom? How does the energy in the third shell of an atom compare to the energy of an electron in the first shell of the same atom? How does the energy on the third shell of an...
An atom is the smallest possible unit of an element. Atoms are considered to be the basic building blocks of matter because they cannot be divided into smaller particles by any chemical process. Atoms are considered to be the basic building blocks of matter because they cannot be divided into...
These are calledsub-atomic particles. They are (obviously) much smaller than the atom itself and have the following properties: Particle Symbol Mass (atomic mass unit u) Charge Proton p 1 +1 Electron e 1/1836≈ 0.0005 ≈ zero -1
Electrons are unique from the other particles in multiple ways. They exist outside of the nucleus, are significantly smaller in mass and exhibit both wave-like and particle-like characteristics. An electron is also anelementary particle, which means that it is not made up of smaller components....
What is the change in atomic mass number when an atom emits an alpha particle? Which elementary particle has the greatest mass? What is the relative mass of an electron? Which subatomic particle has the largest mass? Can relative mass be smaller than atomic mass? What is the mass of a...
This is quite different than an optical microscope which uses reflected light to image a sample. An AFM probe offers a much higher degree of resolution than an optical microscope because the size of the probe is much smaller than the finest wavelength of visible light. In an ultra-high ...
All atoms would like to attain electron configurations like noble gases. That is, have completed outer shells. Atoms can form stable electron configurations like noble gases by: losing electrons sharing electrons gaining electrons. For a stable configuration each atom must fill its outer energy level...
What is an electron? Electrons are tiny compared to protons and neutrons, over 1,800 times smaller than either a proton or a neutron. Electrons are about 0.054% as massive as neutrons, according to Jefferson Lab. Joseph John (J.J.) Thomson, a British physicist, discovered the electron in...

The number of electrons of a nickel atom is 28. As such, the ground-state electron configuration is: {eq}1s^2,\ 2s^2,\ sp^6,\ 3s^2,\ 3p^6,\ 4s^2,\... Learn more about this topic: Ground State Electron Configuration of an Atom | Rules, Terms & Examples ...
