What else can I help you with?
How do periodic trends illustrate stability and change in chemistry?
Periodic trends illustrate how some elements are very reactive while others are stable.
What is the second most reactive metal?
The 2nd most reactive is Cesium after Francium. If you disregard Francium because it is radioactive, then it would be Rubidium after Cesium.
What goes around a circuit?
Charge, in the form of electrons, flow through a circuit. This is called electric current. 1 amp = 1 coulomb of charge per second flowing past a point in the circuit.
What do metals do with electrons?
Metals are elements belonging to first , second or third group. They have one ,two or three valence electrons (electrons present in the last orbit of an atom). They lose this electrons to gain stability as they are highly unstable and by doing so they react . NOTICE: An atom can only lose the electron if an atom of other element is ready to take it.
How many electrons can go in the first second and third shell of an atom?
The first shell can hold a maximum of 2 electrons, the second shell can hold up to 8 while the third shell can also hold a maximum of 8.
How many electrons will the elements have in the second group have on the periodic table?
Elements in the second group of the periodic table, also known as Group 2 or the alkaline earth metals, will have 2 electrons in their outer shell. This gives them a full s subshell and makes them relatively reactive.
What is the chemical family of elements that contains the second group of or most reactive metals?
These metals are called alkaline earth metals.
What are the elements are in the first group have 2 outer shell electrons and are also very reactive?
The elements in the first group of the periodic table, known as the alkali metals, have one outer shell electron and are highly reactive. However, the elements with 2 outer shell electrons that are also very reactive belong to the second group, known as the alkaline earth metals. This group includes elements such as beryllium, magnesium, calcium, strontium, barium, and radium. These metals readily react with water and acids, making them quite reactive, though generally less so than alkali metals.
What group of the periodic table has a 2 plus charge and is reactive?
Group 2 elements of the periodic table have a 2+ charge and are reactive. These elements include beryllium, magnesium, calcium, strontium, barium, and radium. They readily form 2+ cations by losing two electrons in chemical reactions.
How do you determine how reactive an element is based off its atomic number?
the reactivity of depends on the number of its outer shell electrons. one all outer shell electrons are there then there is little reactivity. If the atomic number is 19 then the element will 19 protons and 19 electrons. this means it has 2 electrons in the 1st shell 8 in the second 8 in the 3rd and 1 in the last. as it only has one it will be very reactive =)
Where are the most active elements located on periodic table called?
The most active elements on the periodic table are located in Group 1, also known as the alkali metals. These elements are highly reactive due to their tendency to lose their outermost electron to achieve a stable electron configuration.
Maxuimn of electrons that can fit in an atoms second energy level?
8 electrons. Can be found from the formula 2n2. Where n=the number of the energy level. The number of electrons in the second shell is very important to remember however, because it provides for the octet rule of bonding that almost all elements conform to. Elements wish to have 8 electrons in their outer shell, making the Noble Gases unreactive, and providing for the charges, or oxidation states, of all elements that determine how they bond. Davey.

What group is the second column of the periodic table?
Alkaline earth metals are placed in second column. The elements have 2 valence electrons.
What group of elements consists of non reactive non metals?
Non-reactive elements or compounds are called inert. This is a bit misleading, however - anything can be made to react given the right circumstances. The noble gases are about as close as you can get to truly inert, but even they will react under extreme conditions. >>M.T.<<
What is true about alkaline-earth metals?
Alkaline-earth metals are located in Group 2 of the periodic table and have two valence electrons. They are typically shiny, silvery-white in color, and are less reactive than alkali metals. Alkaline-earth metals form ionic bonds with other elements due to their tendency to lose their two valence electrons.
What are alkaline earth metals on the periodic table?
Alkaline Earth Metals are the elements located in group/family 2, or the second column of the periodic table. They include Beryllium-Be, Magnesium-Mg, Calcium-Ca, Strontium-Sr, Barium-Ba, and Radium-Ra. They have 2 electrons in their outer shell making them very reactive, and are not found freely in nature.
What non metal group is most reactive?
Halogens, hands down. That would be the one second from the right that starts with Fluorine :)
