How many elements on the periodic table are halogens?
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.
What is the charge of ions on Astatine?
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.
Can A Element never contain a compound?
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.
What is the noble gas notation of astatine?
[Xe] 4f14 5d10 6s2 6p5
What element forms 5 different binary compounds with oxygen?
Phosphorus forms 5 different binary compounds with oxygen: phosphorus pentoxide (P2O5), phosphorus trioxide (P2O3), phosphorus dioxide (P2O2), phosphorus monoxide (PO), and phosphorus suboxide (P4O6).
What halogen is located in the second period?
Iodine, element number 53 is the halogen (Group 17) element in period 5.

What was Daltons theory based on?
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.
What compounds can be formed from element X with oxidation numbers 3 and 5 and element Z eith oxidation numbers 2 and 3?
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.
What is the charge of ions on Astatine?
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.
What is the period 5 boron family?
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.
What are the 5 halogens and their symbols?
The 5 natural halogen elements are :- Fluorine (F) Chlorine (Cl) Bromine (Br) Iodine (I) Astatine (At)
What compounds can be formed from element X with oxidation number 3 plus and 5 plus and element Z with oxidation numbers 2- and 3- write their formulas?
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).
Can A Element never contain a compound?
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.
What is boron made of?
