Which group contains only representative elements?
Representative elements, also known as main group elements, include groups 1, 2, and 13-18 on the periodic table. Group 1 contains alkali metals, group 2 contains alkaline earth metals, and groups 13-18 contain p-block elements. These groups are called representative elements because they display a wide range of chemical properties.
What group of elements contains only nobel gasses?
The noble gases group consists of the elements helium, neon, argon, krypton, xenon, and radon. These elements are also known as Group 18 or Group 0 elements on the periodic table. They are characterized by their low reactivity and complete outer electron shells.
Is bromine radioactive?
Fluorine has probable a natural radioactive isotope (F-18) but only as traces.Chlorine has a natural radioactive isotope (Cl-36) but only as traces.Bromine hasn't natural radioactive isotopes.Iodine has probable a natural radioactive isotope (I-125) but only as traces.Astatine has only radioactive isotopes.
What are two elements in group VIIA of the periodic table?
That's not a very valid question becase you could argue that all the elements in that particular group are important. There are at least 4 common ones there, which are carbon, silicon, lead, and tin.
Which groups of elements only have 5 elements?
Considering also very heavy artificial elements this group doesn't exist.
Which family of elements only contains one nonmetal element?
Group 4 (Now 14) of the Periodic Table contains only one non-metal; Carbon (C). All the rest of the elements in this group are metals. The metals in Group 4(14) are;SiliconGermaniumTinLead
Can one element change into a different element?
Yes, but only if it is radioactive. Radioactive elements change into different elements through radioactive decay.
Which group contains element that is liquid at STP?
Group 17 (old name: VIIA) contains Bromine andGroup 12 of the transition elements contains MercuryBoth elements are liquids at room temperature, RTP but only Mercury, Hg is a liquid at STP
Which groups of elements contains only noble gases?
This is the group 18 of the periodic table of Mendeleev.

Are all elements periodically change to become new element s?
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
Which elements posses only one electron in their valence shell and what are they called and what is the radioactive element of this group?
These are the alkali metals; the radioactive one is francium (Fr).
How many elements are made only in a laboratory?
How many radioactive elements are made only in a laboratory?
Which period table group are made up of only gases?
The first period or row contains only elements that are gases at standard temperature and pressure.
What does nobelium and berkelium have in common?
Berkelium and nobelium are members of the actinides group, solid metals, radioactive elements, unstable elements, artificial elements, very difficult to prepare extremely small quantities, only some compounds are known, etc.
What group on the periodic table contains the fewest elements?
These groups are groups 3 to 12 (transition metals) containing each four chemical elements.
