What makes up most of the volume of an atom? What determines an element's electronegativity? What makes one atom different from another atom? How can a charged atom (an ion) attract a neutral atom? An atom has 75 protons, 74 electrons, and 112 neutrons. What is the charge of the atom...
2 翻译一下可以吗1.An atom is made up of positive charges (protons),neutral charges (neutrons) and negative charges (electrons).The protons and neutrons are found within the nucleus of an atom,while we learnt in P08 Curious glow that the electrons are found in different energy levels about...
The important thing to understand about ions is that they are the only types of atom with anet charge. For convenience, chemists (and scientists in general in most cases) take the charge of an electron to be −1, while a proton has a charge of +1. Really these are very specific amou...
A PRECISE measure of the charge on an atom in a molecule is provided by calculating the number of electrons within a sphere of covalent radius using molecular wavefunctions. The results for alkyl substitution suggest that the simple qualitative ideas of the inductive effect may be less simple ...
1 Which statement describes the charge and location of an electron in an atom? (3)(1) An electron has a positive charge and is located outside the nucleus.(2) An electron has a positive charge and is located in the nucleus.(3) An electron has a negative charge and is located outside...

In a neutral atom, the number of electrons is equal to Z, and these orbit the nucleus. The behavior of the electrons defines the chemical reactivities of the elements, and the concentrated positive charge of the nucleus, in turn, determines the behavior of the surrounding electrons. View ...
A neutral atom has the same number of protons and electrons (charges cancel each other out). An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. If the charge is negative, electrons are in excess. ...
