18m. It does not matter what direction the cat walked as long as it walked in a certain direction for said amount of distance
The answer is conductors
You welcome : )
yes, because they are combined in different ratios.
Answer:
Sr<Ca<Be
Explanation:
Br, Ca, and Sr are all elements of same group as they all have 2 valence electrons. As we move down in a group, a new shell is being added that increases the size of the atom. As the size of an atom increases, it is easy to remove the electron from it's outer most shell in it's gaseous state. Since, Be is above Ca and Ca is above Sr. The size increases in the order, Be < Ca < Sr. It means Be is the smallest one of them and so it's hard to remove from it's outer most shell and hence it's ionization energy is higher.
Sr is largest one in these three elements and so it's easy to remove outer most electron from it that means the ionization energy is least. Ca is between Be and Sr.
So, an increasing order of ionization energy is Sr<Ca<Be

It begins to form ice and also on its tail that is ice mixed with rocks and junk but if t where to crash on earth it would come through the atmosphere causing in to burn at amazing speeds. <span />
