How does astatine react with hydrogen?
Astatine can react with hydrogen to form hydrogen astatide (HAt) through a simple displacement reaction. This reaction is similar to the halogens' reactions with hydrogen when hydrogen halides are formed. Hydrogen astatide is a strong acid and highly reactive due to the polar covalent bond between hydrogen and astatine.
In what respect hydrogen is different from halogen?
Hydrogen is a nonmetal element, while halogens are a group of highly reactive nonmetal elements on the periodic table. Hydrogen forms diatomic molecules (H2), while halogens exist as diatomic molecules in their natural state (e.g. Cl2, Br2). Additionally, hydrogen is a gas at room temperature whereas halogens are typically gases or solids.
Is it true that halogens are the basis of all fossil fuels?
No, halogens are not the basis of all fossil fuels. Fossil fuels are primarily made up of hydrocarbons, which are compounds of hydrogen and carbon. Halogens, like chlorine and fluorine, are not typically found in significant amounts in fossil fuels.
What elements will not form an acid when combined with hydrogen?
Only halogens form a binary acid with hydrogen.
Which element will have similar properties to chlorine?
Fluorine (F) will have similar properties to chlorine (Cl) because they both belong to the same group (group 17 or halogens) of the periodic table. They share similar chemical reactivity, electronegativity, and the ability to form -1 oxidation state ions.
Why H cannot be placed in group 1a although its electronic configuraion is similar to group 1a?
It is so because it also resembles the the halogens. The enthalpy of bond dissociation of Hydrogen is quite similar to Halogens. Its properties resemble both alkali metals and the halogens but differ from them too. So, it is not placed with any of them.
Why isn't Hydrogen classified as a Halogen?
Hydrogen is not classified as a halogen because halogens form a distinct group of elements with similar chemical properties, whereas hydrogen is a unique element that does not exhibit the typical characteristics of halogens such as high reactivity and tendency to form salts. Additionally, hydrogen typically forms covalent rather than ionic compounds, further distinguishing it from the halogens.
The fact that hydrogen forms diatomic molecules makes it similar to what family?
The fact that hydrogen forms diatomic molecules makes it similar to the halogen family, which also consists of elements that typically exist as diatomic molecules in their natural state, such as chlorine and fluorine.
Which diatomic molecules have single bonds?
The halogens and hydrogen
How does astatine react with hydrogen?
Astatine can react with hydrogen to form hydrogen astatide (HAt) through a simple displacement reaction. This reaction is similar to the halogens' reactions with hydrogen when hydrogen halides are formed. Hydrogen astatide is a strong acid and highly reactive due to the polar covalent bond between hydrogen and astatine.
Which element is commonly a compound with polonium?
Oxygen, Hydrogen, halogens
Are Hydrogen Nitrogen Oxygen and the Halogens diatomic molecules?
Yes

How are halogens and noble gases alike?
they have similar properties
What are the reaction of other elements from actinium?
Actinium can react with halogens, oxygen, hydrogen.
Why is Hydrogen considered a non metal despite the fact that it behaves as a metal when solid?
Because it is a gas at room temperature. In fact, hydrogen is one of the hardest elements to classify. 1) Hydrogen has one electron in its outer shell and is very reactive (similar to the alkali metals) 2) If it has a full outer shell, it is unreactive (similar to the halogens) 3) If it is exposed to low temperatures and high pressures, it conducts electricity (similar to the transition metals)
Which element is most commonly found as a compound with element polonium?
Oxygen, hydrogen, halogens
