I'm not sure what the temperature has to do with it, but : alkali metal + water --> salt + hydrogen e.g. lithium + water --> lithium hydroxide and hydrogen Hope this helps! xxx
An acid and an alkali/base takes place in a neutralization reaction. For reactions such as redox, precipitation etc. an acid or a base might not take place.
Hydrogen. It is placed with the alkali metals in group 1 because of its electron configuration, but it is a nonmetal.
If you are referring to the alkali metals of Group 1, such as sodium and potassium, the answer is no - in fact with a valence of 1 they are short 7 electrons in their outer level, which is why they react so readily (and violently) with the halogens, chlorine, fluorine and so on.
No, it isn't. One of the clues of telling that is isn't, is that hydrogen is a gas, and If it was an alkali METAL, it would not be a gas, but a metal. Its place on the table does make sense, though; hydrogen tends to behave like other members of it's column in chemical reactions. For example, All of the alkali metals, and hydrogen Combine with oxygen to form the compound X2O, where "X" is either Hydrogen, Lithium, Sodium, Potasium, Rubidium, Cesium, or Francium.
Hydrogen is a group 1 period 1 element. This means it contains only 1 electron. It is place above the alkali metals because if it were with the non-metals it would have to have more electrons. Most diagrams of the periodic table have a divide between it and the alkali metals to remind people of the difference.
Hydrogen is placed with the alkali metals in the periodic table due to its single electron in the outer shell, similar to the alkali metals, which also have one electron in their outermost shell. This similarity leads to comparable chemical behavior, such as the ability to form +1 ions. However, hydrogen is a non-metal and exhibits distinct properties, such as being a gas at room temperature and forming covalent bonds, which differentiates it from the metallic characteristics of alkali metals. This placement reflects its unique properties and behavior rather than a strict classification as a metal.
The noble gasses have a full outer shell of 8 electrons, called on octet (except for helium, which has 2). This is a stable configuration and other elements undergo chemical reactions to approximate it. By contrast the alkali metals have only one outer shell electron which they readily lose in order to go down to the full outer shell below it. The electrons in the lower shells also shield the outer electron from the nucleus, so there is less attraction and the electron is only held loosely. By contrast a noble gas in the same row of a given alkali metal has the same number of electron shells, but the positive charge on its nucleus, so there is a greater force of attraction holding the electrons in place.
Hydrogen is placed in the group 1 because has some chemical similarities and electron configuration (one electron).
Rinsing the conical flask with alkali before use can introduce contaminants or alter the concentration of the solution being prepared. It may also lead to inconsistencies in the experiment if residual alkali affects the reactions taking place. Instead, it's best to use the flask as is, ensuring it is clean and dry, to maintain the integrity of the experiment.
Because they need the ionisation energy to lose the electron in the first place.
Hydrogen posses properties of alkali metals while it also posses properties of halogens .That is why it cannot be placed in any of the either groups ,so it has been given a distinct place in modern periodic table. NOTE Hydrogen does not belong to group 1
Chemical reactions in the body take place in water.
