What group of elements are un reactive?
Balanced or neutral elements. They are more stable because they have a balanced number of protons and electrons.
If you were looking for a very reactive atom would you look in group 1 or 18?
The most reactive chemical elements are in the first group of the periodic table of elements.
Why are group 7 elements very reactive?
Reactions in chemistry are all about the number of electrons in the outer shell of an atom. Generally the more space it has in this shell the more reactive it will be. Group 1 have only 1 electron in the outer shell, group 8 have 8 (8 is the maximum possible so these elements are not reactive).
Why group 12 is more reactive?
The elements from the group 12 are not the most reactive chemical elements.
What is the similarity of the elements in group 3 on the periodic table?
Elements in group three basically have THREE electrons in their outtermost orbitals.However, reactivity increases down the group with Thalium(Tl) being the most reactive as its outtermost electrons are further away from the nucleus.These elements react by losing 3 electrons and therefore they all have a valency of +3.
Elements in the second group have 2 outer shell electrons and are also very reactive They are called?
Elements in the second group have 2 outer shell electrons and also very reactive. What are they called?
Are group 2 elements highly reactive?
Reactivity increases as you go down the group. Radiom is far more reactive than Beryllium.
What group of elements are un reactive?
Balanced or neutral elements. They are more stable because they have a balanced number of protons and electrons.
Are the group 17 elements highly reactive or nonreactive?
Highly reactive because they only have 7 electrons. They need 8 to be a stable element.
What are the names of the four elements of VII A group?
Group 7 elements are halogens. They have seven valance electrons& are highly reactive. They are: -Fluorine -Chlorine -Bromine -Iodine
If you were looking for a very reactive atom would you look in group 1 or 18?
The most reactive chemical elements are in the first group of the periodic table of elements.
Why are group1 and 7 found as compounds?
Group 1 elements have very low electronegativies and group 7 elements have very high electronegativities, so that both are reactive with almost every other element, the group 1 elements by donating electrons and the group 7 elements by accepting electrons.
Why are group 7 elements very reactive?
Reactions in chemistry are all about the number of electrons in the outer shell of an atom. Generally the more space it has in this shell the more reactive it will be. Group 1 have only 1 electron in the outer shell, group 8 have 8 (8 is the maximum possible so these elements are not reactive).
What are the non-reactive and reactive elements in periodic table?
Noble gases (group 18) are the almost nonreactive elements. Group 1 elements are the most reactive metals. Group 17 elements are the most reactive non-metals.
Why group 12 is more reactive?
The elements from the group 12 are not the most reactive chemical elements.
The most reactive elements have how many valence electrons?
The most reactive elements require to lose or gain the least number electron(s) to attain a noble gas structure. These are elements in group one as they need to lose one electron, and elements in group seven as they need to gain one electron.
What does it it mean to say that some elements are reactive and form ions easily whereas others do not?
Elements form ions by either gaining or losing valence electrons. The elements that lose electron(s) and gain electron(s) acquire a positive charge and negative charge respectively. The elements that lose and gain the least electrons require less ionization energy, and are more reactive than elements that need to lose or gain more electrons. For instance, elements in group 1 of the Periodic Table need to lose one electron, and are more reactive than elements in group 2 that need to lose 2 electrons.
