monovalent sodium bromide, as well, so that the two salt ions, sodium ions is positive for Na + and negative ions Br-bromide mustreact lithium oxide with water to give ions Li + Mg have bot valence S 2 and thus gives metals Mg + + ions and metal sulphide valence S-3 and Al AlF3 3ions FK KNO3 + NH4 + NO3-Cl 1 Cl-and NH4 + 1 ION
The charges are indicated in parentheses: Na (+) + Br (-) —> NaBrLi (-) + O (2 -) —> Li2OMg (2 +) + S (2 -) — > MGSAl (3 +) + F (-) —> AlF3K (+) + NO3 (-) —> KNO3NH4 (+) + Cl (-) —> NH4Clpara determine the number of each ion has the type most common denominator between the rates of ion Multiply 2 ‘Cross (find the numbers so the charges cancel wholesale)
NaF (Na +, F-) Li2O (2LI +, O2-) MSG (Mg2 +, S2-) AlF3 (Al3 +, 3F) KNO3 (K +, NO3 (-)) NH4Cl (NH4 (+), Cl – ) I knew that 4.
= Sodium Bromide NaBr -> Na (+) + Br (-) = lithium oxide Li2O (no ions are formed, decomposes in water) Magnesium = MSG sulfur (insoluble in water) = fluoride aluminum AlF3 -> Al (3) + 3F (-) of potassium nitrate, KNO3 = -> K (+) + NO3 (-) of ammonium chloride = AlCl3 -> Al (3) + 3CL (-)///// //////////////////////// ///////////////// how chemistry is a bit like learning basic mathematical tables. It is a process of memorizing routes. It is useful to know what is 7 X 6. Chemists use a single table, the periodic table. It lists all the elements, and the importance of this table are the columns often contain groups of atoms with similar chemical properties. This is particularly true in the left edge bordes.El contain things like sodium, potassium and lithium. All these ions are metals that form with a single positive charge. The right side contains the same “noble gases” such as helium, neon and krypton. These compounds do not form any kind, but the left column contains halogen. These are things such as chlorine, bromine and iodine. These elements are similar to those of sodium and cousins, but are negative halogen ions with a single charge. Move to the right of the right or left of the right and the load is incremented by one. For example, the forms of calcium ions with a positive charge (+2). Fluoride is next to oxygen. It can form a negative ion with a charge of (-2). Things are uniformly distributed along the borders of the periodic table, however. The center of the table contains transition metals “such as iron and chromium. These metals may have unique properties and requirements to achieve what the environment is. This is where the charges come into play balanced. All costs of a molecule must be zero, at least compounds that react together. Calcium has a positive charge (+2) and chlorine has a single negative charge (-1). Therefore, the calcium chloride has the formula CaCl2.Con non-metals such as carbon, oxygen and nitrogen, which must be taken into account is the number of bonds formed. Count backwards from the oxygen and the result is 2, 3 and 4. This means that carbon can form four bonds, and hydrogen in the case, the result is CH4. The sulfur, phosphorus and silicon generally behave the same, but below these elements can not be trusted to behave the same way. Non-metals such as carbon and sulfur tend to form ions. CH4 is unloaded and not iónicos.La last lesson to learn what they have charged functional groups. It’s just a question of memory to get to know a group of nitrate has a negative charge and a positively charged ammonium group 1. Therefore, NH4NO3 ammonium nitrate.
