If you mean elements, there are six members of the halogen family; fluorine, chlorine, bromine, iodine, astatine, and element 117. Element 117 has not yet been officially named. It is currently called ununseptium, Uus, which means 117.
Astatine is in the group 7A of the periodic table. The members of this group all have an ionic charge of -1, so At (astatine) will have a -1 ionic charge.
An element is a substance made up of only one type of atom, while a compound is a substance made up of two or more elements chemically bonded together. Therefore, an element cannot contain a compound within its structure.
The noble gas notation for astatine is [Xe] 4f^14 5d^10 6s^2 6p^5.
Phosphorus forms 5 different binary compounds with oxygen: phosphorus pentoxide (P2O5), phosphorus trioxide (P2O3), phosphorus dioxide (P2O2), phosphorus monoxide (PO), and phosphorus suboxide (P4O6).
The halogen located in the second period of the periodic table is fluorine.

Dalton's theory was based on five principle: 1.An element is fundamentally different from any other element. 2.All atoms of a each element are identical. 3. Atoms from one element can combine with atoms from another element to form compounds. 4. Atoms cannot be created or divided 5. Element are made of small particle called atoms.
Compounds formed from X(III) and Z(II) would have the formula X2Z3, while compounds formed from X(V) and Z(III) would have the formula XZ2.
Astatine is in the group 7A of the periodic table. The members of this group all have an ionic charge of -1, so At (astatine) will have a -1 ionic charge.
The boron family in period 5 of the periodic table includes the element boron (B) and its compounds. Boron is a metalloid element and forms compounds like borates. It also includes elements like aluminum (Al) and gallium (Ga), which exhibit both metallic and non-metallic properties.
The five halogens are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
With element X having oxidation numbers +3 and +5, compounds can form with element Z having oxidation numbers -2 and -3. Some possible compounds could be XZ2 (oxidation numbers cancel out) and XZ3 (oxidation numbers cancel out).
An element is a substance made up of only one type of atom, while a compound is a substance made up of two or more elements chemically bonded together. Therefore, an element cannot contain a compound within its structure.
Boron is a chemical element with the symbol B and atomic number 5. It is a metalloid that can be found in nature primarily in compounds such as borax and boric acid.
The noble gas notation for astatine is [Xe] 4f^14 5d^10 6s^2 6p^5.
Phosphorus forms 5 different binary compounds with oxygen: phosphorus pentoxide (P2O5), phosphorus trioxide (P2O3), phosphorus dioxide (P2O2), phosphorus monoxide (PO), and phosphorus suboxide (P4O6).
