What makes one atom different from another atom? What is the difference between an atom and an element? A chemist masses out 58.933 grams of cobalt. How many grams of boron would she need to mass out to have the same number of atoms in both samples?
How do the atoms of a molecule stay together? What makes one atom different from another atom? What type of bond holds atoms together because of their charge? What is the relationship between the group of an atom and the ion it will most likely form during a chemical reaction?
835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that...
How do atoms make molecules and compounds? Atoms are a bit like people: they usually prefer company to being alone. A lot of atoms prefer to join up with other atoms because they're more stable that way. So hydrogen atoms don't exist by themselves: instead, they pair up to make what...
Some elements have atoms that can include more than one number of neutrons in their nuclei. Isotopes are elements that have the same atomic number (which - as stated above - is what makes them the same element) but different Mass Numbers (A), due to different numbers of neutrons in their...
Learn about atoms, the fundamental unit of matter in the universe. Discover the different parts of an atom, such as the nucleus, proton, neutron,...
But because the atoms are now interacting, the energy levels shift around. In a solid, trillions and trillions of atoms interact with each other. Their individual energy levels smear into energy bands. For a material to conduct, the electrons must be able to jump from lower energy states to...
Our understanding of the atom has come a long way, from classical models that saw it as an inert solid that interacted with other atoms mechanically, to modern theories where atoms are composed of energetic particles that behave unpredictably. While it has taken several thousand years, our knowle...
Quantum computers function similarly to classical computers, but instead of bits, quantum computing uses qubits. These qubits are special systems that act like subatomic particles made of atoms, superconducting electric circuits or other systems that data in a set of amplitudes applied to both 0 and...
