What makes atoms spread out around a central atom? What fundamental particles make up protons and neutrons? What is an elementary particle made of? What kinds of new particles are produced in particle accelerators? Explore our homework questions and answers library ...
All atoms are made from the same bits, which are called subatomic particles ("sub" means smaller than and these are particles smaller than atoms). So if you chopped up an atom of iron, and put the bits into a pile, and then chopped up an atom of gold, and put those bits into a ...
What are the physical properties of pure iron? Describe what kinds of particles or matter you think quarks might be made of. Research is not necessary for this; use your imagination plus logic to arrive at your answer. How can the human body protect against alpha particles?
ElementSymbolAtomsMass % Hydrogen H 1 2.8% Chlorine Cl 1 97.2% These particles are massive with respect to other kinds of radiation; the beta particle, for example, is some 7,000 times smaller. This on the surface might make it seem to be especially dangerous, but in fact the opposite ...
Is anything not made of atoms? (Matter is anything that can be touched physically.) Everything in the universe (except energy) is made of matter, and, so, everything in the universe is made of atoms. An atom itself is made up of three tiny kinds of particles called subatomic particles...
Colloids - heterogeneous mixtures in which one is substance microscopically dispersed evenly throughout another substance (for comparison, the size of the particles of 'solute' are greater than in the case of a solution, but much smaller than in the case of a suspension). There are many natural...
indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. We now know that atoms are made up of three particles known as subatomic particles: protons, neutrons and electrons — which are composed of even smaller particles, such as...
So what are atoms made of? In the middle of each atom is a "nucleus." The nucleus contains two kinds of tiny particles, called protons and neutrons. Orbiting around the nucleus are even smaller particles called electrons. The 115 kinds of atoms are different from each other because they ha...
Quantum computing is a rapidly-emerging technology that harnesses the laws of quantum mechanics to solve problems too complex for classical computers.
Generally, qubits are created by manipulating and measuring quantum particles (the smallest known building blocks of the physical universe), such as photons, electrons, trapped ions and atoms. Qubits can also engineer systems that behave like a quantum particle, as in superconducting circuits. ...
