What does s2- Cl1- K1 and Ca2 have incommon with Ar?
They all have the same electron configuration as the noble gas argon.
S2 Cl1 K1 plus and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
What chemical compound is aluminum chloride?
Al4Cl The compound name is Aluminum Chloride. Al=3- Cl=1+ Chlorine has 7 valence electrons and gains one to become stable making it a positive one charged ion. Aluminum has 3 valence electrons and loses three to become stable making it negative three charged ion.
What is the goal of the criss-cross method in chemistry?
The crossover method for chemistry balances formula units... it's simple once you know how to do it. Here are the steps for the cross over method: Step 1 - In the ionic compounds to be learnt in junior science, there are two parts to the ionic compound - the first is a positive ion (usually a metal e.g. Na1+) and the second is a negative ion (e.g. Cl1-). Step 2 - Using the valency table, write the two ions and their valencies. Step 3 - Now ignore the positive and negative signs. Cross-over the top valency number to the bottom of the other ion symbol. Do this for both. Step 4 - Write the completed formulae with those same numbers at the bottom. Step 5 - If the numbers on each part are the same (e.g. Na1 Cl1 or Mg2 O2), ignore them and rewrite the formulae without them (e.g. Na Cl or Mg O). Step 6 - Brackets may be used around radicals (groups of atoms that are charged e.g CO3). For more information, see Related Links, below.
What is units of measurement and what is the table?
The standard unit of length in the metric system is the meter. Other units of length and their equivalents in meters are as follows:1 millimeter = 0.001 meter1 centimeter = 0.01 meter1 decimeter = 0.1 meter1 kilometer = 1000 meters We symbolize these lengths as follows:1 millimeter = 1 mm1 centimeter = 1 cm1 meter = 1 m1 decimeter = 1 dm1 kilometer = 1 km For reference, 1 meter is a little longer than 1 yard or 3 feet. It is about half the height of a very tall adult. A centimeter is nearly the diameter of a dime, a little less than half an inch. A millimeter is about the thickness of a dime. ---- The standard unit of volume in the metric system is the liter. One liter is equal to 1000 cubic centimeters in volume. Other units of volume and their equivalents in liters are as follows:1 milliliter = 0.001 liter1 centiliter = 0.01 liter1 deciliter = 0.1 liter1 kiloliter = 1000 liters From these units, we see that 1000 milliliters equal 1 liter; so 1 milliliter equals 1 cubic centimeter in volume. We symbolize these volumes as follows:1 milliliter = 1 ml1 centiliter = 1 cl1 deciliter = 1 dl1 liter = 1 l1 kiloliter = 1 kl For reference, 1 liter is a little more than 1 quart. One teaspoon equals about 5 milliliters. ---- The standard unit of mass in the metric system is the gram. Other units of mass and their equivalents in grams are as follows:1 milligram = 0.001 gram1 centigram = 0.01 gram1 decigram = 0.1 gram1 kilogram = 1000 grams We symbolize these masses as follows:1 milligram = 1 mg1 centigram = 1 cg1 decigram = 1 dg1 gram = 1 g1 kilogram = 1 kg For reference, 1 gram is about the mass of a paper clip. One kilogram is about the mass of a liter of water. ---- The following conversions are useful when working with time:1 minute = 60 seconds1 hour = 60 minutes = 3600 seconds1 day = 24 hours1 week = 7 days1 year = 365 1/4 days (for the Earth to travel once around the sun) In practice, every three calendar years will have 365 days, and every fourth year is a "leap year", which has 366 days, to make up for the extra quarter day over four years. The years 1992, 1996, 2000, and 2004 are all leap years. This gives us a total of 52 complete 7 day weeks in each calendar year, with 1 day left over (or 2 in a leap year). The year is divided into 12 months, each of which has 30 or 31 days, except for February, which has 28 days (or 29 days in a leap year). ---- Temperature is expressed in degrees Celsius in the metric system. The boiling point of water (at sea level) is 100°Celsius, or 100°C. The freezing point of water (at sea level) is 0° Celsius. A hot day is about 30° Celsius. ---- We use decimals to specify units of measurement when we need more precision about length, volume, mass, or time. For example, when specifying the height of a person 1.63 meters tall, to say that person is 1 or 2 meters tall doesn't give us a very good idea of how tall that person really is.The prefixes for the different units of length, volume, and mass in the metric system obey the following rules: PrefixMultiply by milli- 0.001 centi- 0.01 deci- 0.1 deka- 10 hecto- 100 kilo- 1000 So for example:1 hectometer = 100 meters1 centigram = 0.01 gram3 milliliters = 3 × (0.001 liters) = 0.003 liters0.9 kilometers = 0.9 × (1000 meters) = 900 meters
How many electrons does Cl1- have?
Chlorine is a non metal element. There are 17 electrons in a single atom.
What has 18 electrons and a charge of -3?
The phosphorus -3 ion. The phosphorus -3 ion gains 3 electrons and acts like argon.
Is CaCl2 ionic or covalent bound?
Of course it's an ionic compound. Calcium loses 2 electrons and forms the calcium cation Ca2+ . Also, each Chlorine atom gains 1 electron and forms the chloride anion Cl1-. This is a reaction between a metal and a non-metal where the loss and gain of electrons is essential and ions were formed, therefore it's ionic ..... hope that's what you were looking for ... ^^ !
What is the electron configuration of Cl1?
what is the electron configuration for Cl 1-
What is the cris cross method of sodium chloride?

What is the chemical formula of saltwater?
Na1+ Cl1- + H+1 OH1- = NaOH + HCl
S2- Cl1- and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
What does s2- Cl1- K1 and Ca2 have incommon with Ar?
They all have the same electron configuration as the noble gas argon.
If barium ions Ca2 have a charge of 2 and hydroxide ions Cl1 have a charge of 1- the compound calcium chloride is?
CaCl2.
Ionic bonds are chemical bonds formed by the?
Ionic bonds are bonds formed between one anion and one cation, or in other terms, one metal and one non-metal. One example is NaCl, Sodium Chloride (the common table salt) that is formed between the Na1+ ion and the Cl1- ion. Together they combine and form what is called the ionic compound, bonded together ionically.
S2- Cl1- K1 plus and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
S2 Cl1 K1 plus and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
