Because all four of those elements are Alkali Metals (first family on the periodic table)
Yes, cesium is expected to react violently with water. This is because cesium belongs to the same group (alkali metals) in the Periodic Table as lithium, sodium, and potassium, which are known to react violently with water due to their highly reactive nature and tendency to form alkaline hydroxides and release hydrogen gas.
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.
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.
One potassium ion is needed to balance the charge of one sulfide ion. This is because potassium has a +1 charge and sulfide has a -2 charge. Therefore, one potassium ion with a +1 charge will neutralize the -2 charge of one sulfide ion, resulting in a net charge of 0.
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
The Bohr model for Lithium is a simplified representation of the lithium atom where electrons orbit the nucleus in fixed energy levels or shells. Lithium has three electrons, with two electrons in the first energy level and one electron in the second energy level. This model helps explain the arrangement of electrons in an atom and their energy levels.
Question is not clear. Please explain clearly so that we can try to answer.
Explain Cm and M.
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.
Explain the purpose of a periodic performance report (two benefits)
Francium is the most reactive metal in group 1 of the periodic table. It is extremely rare and highly unstable, reacting violently with water and air.
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.
because of the electron configuration are different
Yes, a solution of potassium chloride and water will conduct electricity. When potassium chloride (an electrolyte) dissolves in water, it dissociates into potassium ions and chloride ions which can carry electric current.
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
