Be+2 and chlorine , cl-1 from a binary ionic compound with a 1-2 ratio of beryllium ions to chloride ions the formula compound is

Answer : The formula of the binary ionic compound is .

Explanation :

For the ionic compound between ions and ions, we see that the charges on ions and are different, 2+ charge on beryllium ion and 1- charge on chloride ion.The ratio of beryllium ion and chloride ion are given i.e 1:2. That means 1 beryllium ion and 2 chloride ions are combined to form a compound.Now to balance the charges with the lowest number of ions possible. So, two chloride ions to balance the charge on one beryllium ion.

Therefore, the formula of the binary ionic compound is .

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
