Hydrogen is a chemical element with symbol H and atomic number 1. Classified as
a nonmetal
, Hydrogen is a gas at room temperature.
Why is classifying hydrogen difficult?
Hydrogen is a
non metal
but shares a group with metals because of its attribute to form cation. Hydrogen is not considered a metal, even though it does exist in Group I (alkali metals) of the periodic table. … Hydrogen is classified as non-metal. This is because it behaves as non- metal.
How would you classify hydrogen explain your choice?
Explain your choice. Alkali Metals –
Hydrogen has only one valence electron
so it could be classified with the alkali metals. OR Halides – Hydrogen only needs one more valence electron to fill its outer shell so it could be classified with the halides.
Why is hydrogen not a metalloid?
Because hydrogen
is not a soft solid at room temperature and pressure
. In order to be a metalloid, a minimum requirement is that the element must have a reasonably well-defined shape. That is, it must be a solid with properties between those of a nonmetal and a metal.
What classification group is hydrogen and why?
Hydrogen is a
non metal
but shares a group with metals because of its attribute to form cation. Hydrogen is not considered a metal, even though it does exist in Group I (alkali metals) of the periodic table. … Hydrogen is classified as non-metal. This is because it behaves as non- metal.
What family would you classify tin?
Group 14 is
the carbon family
. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level.
In what family would you classify iodine?
iodine (I), chemical element, a member of
the halogen elements
, or Group 17 (Group VIIa) of the periodic table.
Why can hydrogen form an anion so easily?
Why can hydrogen form an anion so easily?
Because hydrogen is a nonmetal and forms H- (hydride anions)
, it is sometimes placed above the halogens in the periodic table. … Hydrogen has a much smaller electron affinity than the halogens. H2 dihydrogen or molecular hydrogen is non-polar with two electrons.
Where is hydrogen found?
Hydrogen is easily the most abundant element
Why is hydrogen not in a family?
When we told you about families, we said that they were groups of elements that react in similar ways. Hydrogen is a very special element of the periodic table and
doesn’t belong to any family
. While hydrogen sits in Group I, it is NOT an alkali metal.
Can hydrogen become a metal?
A pressing matter. Squeezing hydrogen at ultracold temperatures, scientists may have found the
boundary where it becomes solid metal
. … Scientists have already made liquid metal hydrogen—the substance thought to form the interior of giant planets like Jupiter—by ramping up pressure at higher temperatures.
Is gold a metalloid?
| Metals Non-metals Metalloids | Gold Oxygen Silicon | Silver Carbon Boron | Copper Hydrogen Arsenic | Iron Nitrogen Antimony |

Why is hydrogen not an alkali metal?
(Like the other elements in Group 1, hydrogen (H) has one electron in its outermost shell, but it is not classed as an alkali metal
since it is not a metal but a gas at room temperature
.)
What are the Group 2 elements called?
Group 2A (or IIA) of the periodic table are the
alkaline earth metals
: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
What is the symbol of tin?
The symbol Sn for tin is
an abbreviation of the Latin word for tin, stannum
. The periodic table is made up of 118 elements.
Who named tin?
Tin gets its name from
the Anglo-Saxon language
. The symbol “Sn” comes from the Latin word for tin, “stannum.” Tin has ten stable isotopes.
