Neon and Argon are "noble gases" which are stable as single atoms - in fact it is extremly difficult to form polyatomic molecules that include any of the noble gases. The total list of "noble gases" in order of asceding atomic weights: Helium, Neon, Argon, Krypton, Xenon, and Radon. In theory, there might be another "noble gas" at atomic number 118 (temporary IUPAC name "Ununoctium", but the radioactive ununoctium atom is very unstable, and since 2002, only three atoms (possibly four) of the isotope 294Uuo have been detected. Obviously not much is known about that element but some theoretical calculations have been made which make some interesting predictions about it including that it is probably NOT a noble gas like all the other elements in the same column of the Periodic Table, i.e. helium, neon, etc. It was originally predicted to be a gas but is now predicted to be a solid under normal room temperature and pressue.
Chlorine and Bromine are halogens and are stable as diatomic molecules, i.e. Cl2 and Br2, at normal room temperature and pressure.
What else can I help you with?
Which of the following elements is characterized purely as a non-metal?
Nonmetals are: hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon, radon, bromine), carbon, phosphorus, sulfur, selenium, and iodine.
Helium argon and radon are members of the halogen family?
False. Helium, argon, and radon are noble gases, not members of the halogen family. Halogens include elements like fluorine, chlorine, bromine, and iodine.
What element is a noble gas with 22 neutrons?
The element is argon and the isotope is 18Ar40
What is one less proton than argon?
Chlorine, with the atomic number 17 has one less proton than argon, with the atomic number 18. The atomic number is the number of protons.
Which are the 22 non-metals?
Okay: so there's this "zigzag line" on the periodic table and all elements to the right of that line are nonmetals. A few touching the line are considered metalloids but look the right of that things and there are your nonmetals for you. They are: Hydrogen Helium Carbon Nitrogen Oxygen Fluorine Neon Phosphorus Sulfur Chlorine Argon Selenium Bromine Krypton Iodine Xenon Astatine Radon
Which element is most likely a nonmental?
Any of the Halogens (Fluorine, Chlorine, Bromine, Iodine, and Astatine) or Noble Gases (Helium, Neon, Argon, Krypton, Xenon, Radon) would be considered a nonmetal.
Which of the following elements is characterized purely as a non-metal?
Nonmetals are: hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon, radon, bromine), carbon, phosphorus, sulfur, selenium, and iodine.
Is argon in the family of halogen?
No, argon is not in the halogen family. Halogens include elements like fluorine, chlorine, bromine, iodine, and astatine, which are part of Group 17 of the periodic table. Argon is a noble gas and belongs to Group 18.
How many nuetrons are in the following elements oxygen bromine helium argon manganese and silicon?
Oxygen=8 Bromine=45 Helium=2 Argon=22 Manganese=30 Silicone=14
Are argon in bromine similar?
Argon and bromine are not similar. Argon is a colorless, odorless gas that belongs to the noble gas group on the periodic table, while bromine is a reddish-brown liquid halogen. Argon is chemically inert and does not readily react with other elements, while bromine is a highly reactive element.
Helium argon and radon are members of the halogen family?
False. Helium, argon, and radon are noble gases, not members of the halogen family. Halogens include elements like fluorine, chlorine, bromine, and iodine.
Is argon a diatonic element?
No. argon is a monoatomic element. It does not combine with other elements or with itself.
What element is most like chlorine?
Bromine is the element most like chlorine because they belong to the same group in the periodic table. They have similar chemical properties and react in similar ways with other elements.
Does Argon have more protons than chlorine?
Yes. The atomic number of chlorine is 17 and it has 17 protons. The atomic number of argon is 18 with 18 protons.
What gasses are the world made of?
The world's atmosphere includes Nitrogen, Oxygen, Hydrogen, Carbon Dioxide, Helium, Argon, Radon, Fluorine, Chlorine, Bromine, Iodine, Neon, and more.
Is oxygen chlorine silicon or argon?
argon
What elements is the most electronegative Argon Chlorine Phosphorus or Sulfur?
The most electronegative element among Argon, Chlorine, Phosphorus, and Sulfur is Chlorine. Chlorine is more electronegative than Phosphorus and Sulfur and Argon is an inert noble gas with very low electronegativity.
