How to know if an atom is stable or reactive? What is a nuclide? What is a neutral atom? What is an atom that has more protons than electrons? If an atom contains 14 protons, it is an atom of which element? Which is a substance that is made up of only one type of atom? What...
Why is calcium generally more reactive than magnesium? What are some properties of artificial elements? What are the properties of methane? What do beryllium, magnesium and calcium have in common? What are some of neon's chemical properties?
Silicone is generally nonreactive, and silicone polymers are biocompatible, so they're used in things that stay in prolonged contact with the body, such as prosthetics and some implants. Silicon is also used in liquid solutions of calcium or sodium silicate, the latter of which is an ...
compound. As a result, Potassium Bromide is formed, whereas a molecule of Iodine is given out. This reaction takes place because Bromine is more reactive than Iodine, which is why it replaces it. Because the replacement ions have a negative charge, this reaction is an example ofanionic ...
What type of element is lead? In other words, what is it classified as on the periodic table? What element is the most reactive in the periodic table? Explain why. Which of the following groups of elements are likely to have substances that have both metallic and non-metallic properties?
What is thermite process and its uses? Thermite process : When highly reactive metals such as Sodium, Calcium, Aluminium etc., are usedas reducing agents they displace metals of lower reactivity from thecom-pound. These are exothermic reactions. The amount of heat evolved is so large that the...
Which element is more reactive, Iodine or Astatine? Why does chlorine have a higher electronegativity value than krypton? What H+ ions of an acid and the OH- ions of a base means. What is the difference in macroscopic properties between covalent and ionic bonds?
Which do you expect to be more reactive, lithium or potassium? Explain. Describe how the elements potassium and sodium got their names. Describe some uses of lithium and its compounds. What are some common uses of sodium hydroxide? What is the chemistry behind these elements to give them ...
Sodium (Na) Potassium (K) Rubidium (Rb) Caesium (Cs) Francium (Fr) Answer and Explanation:1 All alkali metals possess one valence electron and thus, form monovalent ions i.e.,M+after losing their one... Learn more about this topic: ...
The increase in reactivity correlates to a decrease inelectronegativity(increase in electropositivity.) So, just by looking at theperiodic table,you can predict lithium will be less reactive than sodium, and francium will be more reactive than cesium and all of the other elements listed above it ...
