Chapter 17 Can we get those electrons moving? Induction The transfer of electron or electricity without touching A group of cells put together BATTERy A group of cells put together Electric Discharge The release of electricity from a source – like a cumulonimbus cloud Static electricity Electric ch...
Why do atoms of the same group form ions of the same charge? (a) They have the same number of valence electrons (b) They have the same number of protons (c) They have the same number of electrons (d) They have the same number of valence neutrons (e) They ...
Do neutrons matter in electrostatics? How fast are atoms in a particle accelerator? Does quantum electrodynamics have electric fields? What is cyclotron orbit? Is an electron an elementary particle? Does electric potential obey superposition?
dense region consisting of protons and neutrons at the center of an atom. The protons are positively charged, and neutrons are electrically neutral. (Scientists have since learned protons and neutrons are in turn made up of particles called quarks). The other part of atoms...
Isotopes areatoms that have the same numbers of protons but different numbers of neutrons. An ion is an atom that has gained or lost electrons, so it now has more or fewer electrons than it does protons. So an ion has a negative or positive charge. ...
Still, no one knows how those protons and neutrons (together known as nucleons) behave inside an atom. Outside an atom, protons and neutrons have definite sizes and shapes. ... The nucleons, confined in their movements, have very little energy. They don't bounce around much, restrained ...
Artificial isotopes can be created by bombarding existing isotopes with “slow” neutrons, some of which stick to the nuclei of the target material’s atoms. Just like the creation of particles, this is a random andextremelyinefficient process. Technically you can make oxygen, a...
Boron neutron capture therapy (BNCT) is an attractive approach to treat invasive malignant tumours due to binary heavy-particle irradiation, but its clinical applications have been hindered by boron delivery agents with low in vivo stability, poor biocom
Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. True or False? The F^(-) ion is larger than the F atom. True False The number of waves made by an electron moving in an orbit having maximum magnetic quantum num...
Why do you have to dry the aspirin before weighing it and making calculations? Why are electrons affected by the addition of heat, light, or electricity but protons and neutrons are not? Why do transition elements form colored compounds?
