What is the halogen that is in period 5?
Go to Period 5, go all the way to the Halogens, what is there? Iodine. Thus, your answer.
Which halogen is found in period?
Chlorine
It is a nonmetal, and is one of the few elements that can form diatomic molecules (F2). Chlorine is a halogen in group 17 and period 3. It is very reactive and is widely used for many purposes, such as as a disinfectant. Due to its high reactivity, it is commonly found in nature bonded to many different elements.
What is the halogen in the second period?
The elements in period 2 often have the most extreme properties in their respective groups; for example, fluorine is the most reactive halogen, neon is the most inert noble gas, and lithium is the least reactive alkali metal.
Is Iodine a period 5 halogen?
The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What is the last element in Period 4?
The fourth period contains 18 elements beginning with potassium and ending with krypton – one element for each of the eighteen groups.
What are 3 elements in the same period?
The third period contains eight elements: sodium, magnesium, aluminium, silicon, phosphorus, sulfur, chlorine, and argon. The first two, sodium and magnesium, are members of the s-block of the periodic table, while the others are members of the p-block….Period 3 element.

Which element in Period 2 has most mass?
The element neon, in period 2, has the most mass.
Is a noble gas found in the 5th period?
Argon and helium can not be considered rare as argon makes up about 1% of our atmosphere and helium is the second most abundant element in the known universe….Noble Gases.

Which element is in Group 5 period 4?
Group 5A (or VA) of the periodic table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi).
What are the names of the halogens in the periodic table?
This article is about the chemical series. For other uses, see Halogen (disambiguation). The halogens ( / ˈhælədʒən, ˈheɪ -, – loʊ -, – ˌdʒɛn /) are a group in the periodic table consisting of five chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What are the properties of Group 7 halogens?
Group 7 elements form salts when they react with metals. The term ‘halogen’ means ‘salt former’. This table summarises some of the properties and uses of three halogens: Iodine forms a purple vapour when it is warmed.
Which is the first element of period 4?
This isn’t possible in further periods due to existence of f-subshells starting from n = 4 . Potassium (K) is an alkali metal, placed under sodium and over rubidium, and is the first element of period 4. It is one of the most reactive elements in the periodic table, therefore usually only found in compounds.
Is the element 117 in the same column as the other halogens?
Element 117, which has the placeholder name of ununseptium, might have some properties in common with the other elements. Even though it is in the same column or group of the periodic table with the other halogens, most scientists believe element 117 will behave more like a metalloid.
What do all the halogens have in common?
- They all form acids when combined with hydrogen.
- They are all fairly toxic.
- They readily combine with metals to form salts.
- They have seven valence electrons in their outer shell.
- They are highly reactive and electronegative.
- They all exist as diatomic molecules (two atoms) when in their pure form.
What are some examples of halogens?
The halogens are a series of non-metal elements from group 17 of the periodic table (formerly VII). The halogens include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What are all the halogens?
Halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). They were given the name halogen, from the Greek roots hal – (“salt”) and – gen (“to produce”),…
What family are the halogens in?
The halogens are the family of chemical elements that includes fluorine (atomic symbol F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The halogens make up Group VIIA of the Periodic Table of the elements.
