Homogeneous mixtures can not be separated, heterogeneous mixtures can.
Neutrons have a neutral charge
Neutrons have no charge.
are in probable cloud locations.
The outer or valence electrons are the ones involved in bonding.
Find out the mass number (A) of the specific isotope of the element. Find out the atomic number (Z) of the element (e.g. from the periodic table).
Number of Neutrons, N = A-Z.
electrons in the outer shell have more energy than those of the inner shells. But electrons in inner shells are closer to the nucleus.
Reason: APE EGS
Families or _GROUPS_ of elements are similar due to similarities in their number of valence electrons.
Wax, like all matter, comes in many phases. What are the three possible phases?
gas. liquid, and solid
it needs six more electrons to have a full outer valence shell.
the use of money to buy your way into power
there are ten quarters in two and a half.
two quarters make a half and eight quarters make two. 8quartesr+2quarters=10quarters
The elements in this part of the periodic table want to gain electrons to get to a noble gas configuration - not lose them. To lose electrons is very energetically unfavorable (high ionization energies).
The Halogens have seven valence electrons.
