Which group of metals is characterized by a single valence electron and reactive atoms?
Alkali metals
What is the element in the first group that are reactive highly and has on electron shell?
metals
Why are the metals in the first group of the period table so reactive?
These metals lose easily an electron.
Most reactive group in periodic table?
The most reactive goup in the metals is the Alkali metals (Group I) The most reactive non-metal group is Group 17 or VIIA) the Halogens. It is difficult to say which of the two groups is more reactive. Chemists will say that Flourine is the most reactive element. Note that Group 18 is the least reactive, most stable.
Why are alkali metals more reactive than other metals?
Alkali metals are more reactive as they are in group 1 and therefore has only one valence electron. With only one valence electron, its easy for them to achieve inert configuration/ noble gas configuration, which makes them so reactive.
Where in the periodic table are the very reactive non metals that easily form salt compounds with metals?
In the fluorine group or group 17. Its the column one from the right. The are reactive with metals because they want to gain one electron where as metals want to loose them.
What is the most reactive metals that are found in a group?
Both the alkali metals and halogens because they only need one electron, or only need to lose 1 electron
Which group of metals is characterized by a single valence electron and are very reactive atoms?
Alkali metals
What is the trend for first ionization energy for the alkali metals?
Within the alkali metals, or group 1, the ionization energy trend is that ionization energy decreases as you move down the group from top to bottom. This is because with each step down, you add an energy level, therefore the one valence electron is farther and farther from the atom's nucleus. So, the attraction between the nucleus and that electron (its electronegativity) decreases. This makes it easier (requires less energy), making the element more reactive. For example, cesium is more reactive than rubidium, which is more reactive than potassium, which is more reactive than sodium...
What is the most reactive group of elements?
It is in Group 17 that you will find the most reactive elements. These elements all lack only one electron from having that "magic" electron configuration of the inert gases. That makes these elements very "hungry" to get that "last electron" so their electron structures become more stable.
How reactive is the halogen group?
The halogens are the most reactive non-metals. They need only 1 additional electron to complete their octet.
What are the elements in the first group that have one outer shell electron and that are very reactive called?
The elements in this group are called Alkali Metals.
