Which 2 elements are gases at STP?
hydrogen, nitrogen, oxygen, fluorine, and chlorine are all gases at STP
Where are most gases are found on the periodic table found?
"Gas" is a state of matter, any element has a gas phase if you heat it. However at STP (room temperature) there are 11 gaseous elements in the Periodic Table.====================• hydrogen (H)• nitrogen (N)• oxygen (O)=================== The halides• fluorine (F)• chlorine (Cl)===================The Noble Gasses• helium (He)• neon (Ne)• argon (Ar)• xenon (Xe)• radon (Rn)• krypton (Kr)
What is an element in group 2 at stp?
An example of an element in Group 2 at STP (standard temperature and pressure) is beryllium (Be). Group 2 elements are also known as alkaline earth metals, and they are located in the second column of the periodic table. At STP, beryllium exists as a solid with a melting point of 1278°C and a boiling point of 2970°C.
Which element exists as monatomic molecules as stp?
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
How many gases in all are there in the periodic table?
There are 11 gases in the periodic table and they are : Hydrogen, Helium, Neon, Argon, Krypton, xenon, radon, chlorine, fluorine, oxygen and nitrogen :D11Hydrogen (H), nitrogen (N), oxygen (O), Fluorine (F), Chlorine (Cl), Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn)There are eleven elements that are naturally present as gases: hydrogen, nitrogen, oxygen, fluorine, chlorine, helium, neon, Argon, krypton, xenon, and radonThere are 11 gaseous elements in the Periodic Table.• hydrogen (H)• nitrogen (N)• oxygen (O)• fluorine (F)• chlorine (Cl)• helium (He)• neon (Ne)• argon (Ar)• xenon (Xe)• radon (Rn)• krypton (Kr)There are 11 known gaseous elements: hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon, and radon. Element 118 may be gaseous as it is in the same family as the noble gases, however that is not known due to the short half-life.
What periodic table group has elements that are all gases at stp?
Periodic Group 18(0) has all gaseous elements in it, commonly known as the noble, or inert gases.
Which period contains the most elements that are all gases at STP?
The noble gases in Group 18 contain elements that are all gases at standard temperature and pressure (STP). Therefore, the period that contains the most elements that are all gases at STP is the third period.

What are helium and oxygen?
They are both elements, they are both gases at STP.

Group 2 elements are also known as alkaline earth metals, and they are located in the second column of the periodic table. At STP, beryllium exists as a solid with a melting point of 1278°C and a boiling point of 2970°C.
Which group contains an element at is liq at STP?
Group 12 of the periodic table contain mercury (Hg).
Uranium hexafluoride uf6 is one of the densest gases known what is its density at stp if 1 mole occupies 22.4 l report answer in grams per liter g l use a periodic table as needed?

Is table salt made up of metals or gases?
No. Table salt is composed of two elements which are, in their elemental state under "ordinary" circumstances (STP), a highly reactive metal and a highly reactive poisonous gas.
Is neon a metal semimetal or nonmetal?
ITS A NON METALIt's a gas, one of the so called noble gases because of its reluctance to form compounds with other elements at STP. Other noble gases at STP include helium, argon, krypton, xenon and radon
Which element exists as monatomic molecules as stp?
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
Which halogens are gases at STP?
At standard temperature and pressure (STP), fluorine (F2), chlorine (Cl2), and bromine (Br2) are gases. Iodine (I2) is a solid at STP.
