Lithium sodium and potassium all react violently with water knowing this and looking at the periodic table would you expect cesium to react violently with water as well explain why or why not?

Because all four of those elements are Alkali Metals (first family on the Periodic Table)

Does the periodic table explain the shell model or does the shell model explain the periodic table?
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.
Explain the difference between atomic number and mass number?
Atomic number is the number of protons in the nucleus of an atom while the mass number is the sum of the protons and neutrons in the nucleus of an atom. for example lithium has an atomic number of 3 and a mass number of 7. Therefore lithium has 3 protons and 4 neutrons.
Explain how you would prepare a saturated solution of potassium nitrate in water?
Add potassium nitrate to distilled water while stirring continuously; stop adding potassium nitrate once the chemical becomes saturated and stops dissolving in the water. Filter the solution into an evaporating dish and measure the temperature of the solution. Measure the temperature and carefully heat the solution under low heat. Weigh the potassium nitrate to determine its solubility. You should find that approximately 36 g of potassium nitrate can be dissolved in 100 ml of water at room temperature (25 degrees Celsius). santosh kumar.batchu santoshkumar@gmail.com
How many potassium ions are needed to balance the charge of one sulfide ion Explain?
Two. the sulfide ion is S2- so two K+ ions are required to balance the charges
Can you explain what happens to the particles of potassium chloride when they dissolve in the water?
when particles of KCl are put in water, they dissolve because KCl being a polar ionic compound, its ions separate and in aqueous solutions, water molecules surround these ions with the partially positive hydrogen ions closer to the chloride ions and the partially negative oxide ion towards the potassium ion but the electron cloud is bigger on the side of the chloride ion since it's more electronegative and the attraction between the hydrogen and the chlorine and between oxygen and potassium becomes stronger than that between potassium and chlorine hence the two ions [potassium and chloride] are pulled apart forming ions in the solution
Will substituting lithium nitrate for lithium cl work for an experiment about solubility patterns for group 7 anions we normally add libr to nacl and potassium iodide and nafl where nafl is insoluble?
Question is not clear. Please explain clearly so that we can try to answer.
What weight of lithium bromide would be required to make Cm of M lithium bromide solution?
Explain Cm and M.
How does atomic number explain the arrangement of the periodic table?
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
What is the purpose of periodic performance reports in real estate?
Explain the purpose of a periodic performance report (two benefits)
Explain why potassium and calcium are both in period 4?
Potassium and calcium are both in period 4 of the periodic table because they both have 4 electrons in their outermost energy level. This means they both have the same number of protons and the same number of electrons, which puts them in the same period. Additionally, they both have the same number of shells, which is why they are both in period 4.
What are iron potassium and iodine?
They are elements in the periodic table. Iron (Fe) is used for too many things to explain quickly. Potassium (K) is a very flammable alkali-metal that is found in bananas, it's so easy to cut you could use a butter knife. Iodine (I) compounds are important in organic chemistry and very useful in medicine and photography however it is also a poison that can kill.
Explain why the table of elements is periodic?
because of the electron configuration are different
Explain why lithium and beryllium form ions with different charges?
The number of valences electrons is different.
Explain how information about an element's physical state at room temperature will help you fill in the partial periodic table?
Explain how information about an element's physical state at room temperature will help you fill in the partial periodic table.
How does the periodic nature of tides explain why tiddal power is not a steady source of energy?
You have sullivans?
How do you explain what an element is to kids?
an element is a material on the periodic table that cant be broken down
Can anybody explain the process of Conversion of lithium into lithium chloride?
The ore is heated at 1373 K to convert into less dense and more friable (easily crumbled) form. It is then washed with Sulphuric acid at 523 K and leached with water to give Lithium sulphate monohydrate (Li2SO4.H2O). It is then treated with sodium carbonate solution and HCl, which gives insoluble Lithium carbonate and finally Lithium chloride. source : http://www.examville.com
