Hydrogen is placed in the same group as the alkali metals because like the other alkali metals, it only has one valence electron (electron in the outermost energy level of the atom). Even so, many consider Hydrogen separately because unlike the other alkali metals, it cannot lose its one and only valence electron. Mendaliv put Hydrogen there because it could not go anywhere else.
sodium, calcium, magnesium, aluminium, zinc, iron, tin and led are metals more reactive than hydrogen.
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
There are five reactive metals: lithium, sodium, potassium, rubidium, and cesium. These metals are located in Group 1 of the periodic table and are highly reactive due to their tendency to lose an electron easily.
The most reactive metals on the periodic table are located in Group 1, also known as the alkali metals. These elements have a single electron in their outer shell, making them highly reactive as they readily lose that electron to form positive ions. Examples include lithium, sodium, and potassium.
The most reactive element of part of Group 1 is the one with the highest atomic number. If hydrogen is considered to be in period 1, then the answer to the question is sodium. If instead hydrogen is considered to be in a 0th period, then the answer to the question is potassium.
Group 1 (for metals) and group 17 (for non metals).
Group 1 (for metals) and group 17 (for non metals).
These chemical elements are located in the group 17.
The most reactive metals are in the group 1 of the Periodic Table - the alkali metals.
sodium, calcium, magnesium, aluminium, zinc, iron, tin and led are metals more reactive than hydrogen.
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
Most Of The Reactive Metal Are The Alkaline Metals - Which Are In Group 1 Of The Periodic Table.
In group 1.
There are five reactive metals: lithium, sodium, potassium, rubidium, and cesium. These metals are located in Group 1 of the periodic table and are highly reactive due to their tendency to lose an electron easily.
Hydrogen is a non-metal; it's in group VII
These chemical elements are located in the group 17.
The alkali metals are located in Group 1 of the periodic table, also known as the first column. This group includes elements such as lithium, sodium, and potassium. Alkali metals are known for their highly reactive nature due to having one electron in their outermost shell.
