WebJan 17, 2024 · To understand why noble metals are some of the least reactive metals, it is important to know their electronic configuration. The chemical reactivity of elements is affected by the arrangement of electrons around the nucleus, which allows the atom to remain stable. Stability is attained when the element has completely filled electron shells. WebFeb 23, 2024 · The most reactive metals have the greatest tendency to lose electrons to form positively charged ions. Metals, therefore, become more reactive as they are located further to the left on the periodic table. Based on the activities of the metals, the four metals can be separated into three different categories: Reactive in both acid and water (i ... list of songs

WebReason: Decomposition reaction involves breakdown of a single reactant into simpler products. Q27. Assertion: Silver chloride turns grey in presence of sunlight. Reason: Silver is one of the least reactive metals. Q28. Assertion: Changing of colour of copper oxide to copper is an example of reduction. Reason: Hydrogen is removed. WebAug 13, 2024 · The most reactive element in group 1 is casesium because as we come from top to bottom, the size of atom is increased in the parallel with the number of electron, so the strength to held the electron decrease, and we know that all alkali metal have one electron in outer most shell so it can be very easy to remove that electron from casesium. WebChoose 2 options. answer choices. There is no visible change because no displacement reaction took place. Copper, being less reactive than silver, cannot displace silver from silver nitrate. Silver crystals were formed on copper coil, because copper (being more reactive than silver) displaced silver from silver nitrate. Question 31. list of some onion sites
