You may be confused about whether the stability of an atom is related to its electrical charge. An atom that gains or loses an electron to form an ion is more stable than a neutral atom if the ion gets a full electron shell by forming the ion. Because oppositely charged ions attract eac...
An electrically neutral group of two or more atoms held together by chemical bonds is the most basic definition of molecule. In that sense, no, by nature, a molecule can not be formed from a single atom. Q5 What is the structure of an atom?
Compared to the tail of electrically charged atoms, the tail of neutral dust particles is relatively A. long B. curved C. unpredictable D. bright E. Questions 20-29 F. m. they may have allowed more young to survive each year, gradually increasing the populations of favored species As ...
aIn chemistry, a molecule is defined as a sufficiently stable, electrically neutral group of at least two atoms in a definite arrangement held together by very strong chemical bonds. It can also be defined as a unit of two or more atoms held together by covalent bonds. Molecules are ...
Why are electrons allowed to fall on a crystal plate for diffraction? Why are objects with vast number of electrons normally not electrically charged? Give a reason why all mesons are formed from a quark and an anti-quark. If the space inside an atom is not a vacuum, then what is it?
they use not electrically neutral photons, but elementary particles carrying a charge, usuallyelectrons. Experiments then show that when electrons have relatively low energies, atomic nuclei behave as if they were made of nucleons (i.e. protons and neutrons), whereas at high energies, partons (...
An atom has an equal number of protons and electrons, making it electrically neutral. The atomic number Z is the number of protons in the nucleus. The electron models employed in semiconductor electronics are the classical model and the quantum-mechanical model. ...
if everything inside you was electrically neutral, it could be packed into a neutron star, whose density is traditionally measured in tons per matchbox-ful … it's only the electrical forces that keep you in shape. Stay solid! ™FAQ...
is neutral, then so long as the number of protons and electrons are equal then their charges cancel out and atoms are electrically neutral. Remove an electron from around an atom, however, and this upsets the balance between the cumulative charges of the electrons and the protons, and the ...
