a)would you expect beryllium, element 4, to react vigorously with water? Explain.
b)what is the relationship between the properties of elements and their position on the periodic table?
PLEASE HELP ME WITH THIS!!!!!!!!!!

A) "Beryllium metal does not react with water or steam, even if the metal is heated to red heat."
WHY? "Beryllium is reluctant to burn unless it is in the form of dust or powder. Beryllium has a very strong (but very thin) layer of beryllium oxide on its surface, and this prevents any new oxygen getting at the underlying beryllium to react with it."
B) The layout of the periodic table demonstrates recurring ("periodic") chemical properties. Elements are listed in order of increasing atomic number (i.e. the number of protons in the atomic nucleus). Rows are arranged so that elements with similar properties fall into the same vertical columns ("groups"). According to quantum mechanical theories of electron configuration within atoms, each horizontal row ("period") in the table corresponded to the filling of a quantum shell of electrons. There are progressively longer periods further down the table, grouping the elements into s-, p-, d- and f-blocks to reflect their electron configuration.

Ok this is one the things that if you learn, you can go far in chemistry. Metals are on the left and Non metals on the right. They love to get together and make ionic compounds. metals are more likely to react if they are on the extreme right and down on the periodic table. For example, potasium is more reactive than sodium and cesium is even more reactive. On the far right are the noble gases. It is extremely unusual for them to react with any thing, on their left is a group called the halogens, They react with everthing. They are more reactive at the top. So flourine is more reactive than chlorine. Now with what I have told you, you can figure it out, but here is a hint. Magnesium is used in helicopter and bicycle parts on which it rains. How will berylium react?

a) No, too high ionisation energy
b) based on electronic configuration.

i dunno abt the 1 quest .....sry......
ur 2 ques...........the elements belonging to the same group have same chemical properties.........so u c the position of element determine its property...........
