a list of representative metals

Metal Electrodes - A metal ion system in which the metal is in equilibrium with its own ions in solution is called a metal electrode. Example: Zn rod is dipped in ZnSO 4 solution constitutes a Zn electrode, which is represented as Zn/Zn + 2 . When e..

Nitrogen readily combines with highly electropositive metals (Group 1), even at room temperature, to give nitrides. For example,..

The Reactivity Series of Metals - Although most metals are usually electropositive in nature and lose electrons in a chemical reaction they do not react with the same vigour or speed. Metals display different reactions towards different substances. The greater the ease..

. Any atom with this configuration will be in the minimum state of energy, hence stable. Atoms try to attain the octet or the duplet configuration by either loss or gain of electrons. Metal atoms tend to lose electrons. Non metal atoms tend to gain electrons. Example: Lithium ha..

The energy required per mole of sodium is 'enthalpy of sublimation' which is represented by ( Hs). This step is energy consuming process...

The wingspans of a few species of butterflies are listed. 90, 35, 30, 35, 60, 37, 60, 18, 20, 70, 65 Which box-and-whisker plot best represents the data? => Plot 3 or Plot 2 or Plot 1 or Plot 4..

In metals, the conduction band and valence band partly overlap each other and there is no forbidden energy gap. In insulators, the conduction band is empty and valence band is completely filled and forbidden gap is quite large = 6 eV. No electron from valence band can cross over to c..

The temperatures (in degrees Fahrenheit) recorded in 9 cities are represented in the following list. 51, 60, 75, 52, 61, 87, 79, 77, 80. Find an appropriate stem and leaf plot for the given data. => Plot 2 or Plot 3 or Plot 1 or Plot 4..

A symbol represents one atom of an element. Example: H stands for one atom of hydrogen. However, if a symbol has a subscript and a superscript, as given along side, then more in formation can be derived from it...

The temperatures (in degrees Fahrenheit) recorded in different cities are represented in the following list. 51, 60, 75, 52, 61, 87, 79, 63, 66, 77, 80, 54 Pick an appropriate stem and leaf plot for the given data. => Plot 1 or Plot 4 or Plot 3 or Plot 2..
