Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge. You can determine the number of electrons in anionif you know its charge. A cation carries a positive charge and has more protons than electrons. An anion carries a negative...
An electron is a negatively charged subatomic particle that can be either bound to anatomor free (not bound). An electron that is bound to an atom is one of the three primary types of particles within the atom -- the other two areprotonsandneutrons. Together, protons and electrons form an...
Answer to: Atoms with more than two electrons achieve a noble gas structure by sharing enough electrons to attain an octet. Define the octet rule...
An atom has three types of very tiny particles called protons, neutrons and electrons. The center of an atom is called the nucleus, and it is made up of protons and neutrons. The electrons in an atom fly around and above the nucleus in a cloud-like formation. The protons have a positiv...
Figure 14.1 illustrates a simplified representation of an atom; most electrons occupy orbitals with much more complicated shapes than spheres as implied here [3]. This familiar representation has a central circle with the symbol of “+” representing the positively charged nucleus with “n” charge...
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 atom. ...
A good example is the OH bond in which the oxygen atom is more electronegative. Electronegativity refers to the ability of a nucleus to attract shared electrons. Because O is more electronegative than H, the resulting OH bond is polar, with more negative charge around the O atom than the H...
So, you know you need 6 protons to make a model of carbon. To make a carbon atom, make 6 protons, 6 neutrons, and 6 electrons. Bundle the protons and neutrons together to make the nucleus and put the electrons outside the atom. Note that the model gets slightly more complicated when...
