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.
Which group contains only radioactive elements?
The actinoids (formerly actinides) are all unstable metallic elements. The period 7 elements with atomic numbers from 89 (actinium, for which the group is named) through 103 comprise these elements. A link can be found below.
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.
Of the following the group that contains elements that are the most reactive is the?
Group 1 (alkali metals) is the most reactive group of elements. This group includes lithium, sodium, potassium, rubidium, cesium, and francium. They are highly reactive due to having only one electron in their outermost shell, which they readily donate to form stable compounds.
Are the elements Cu a representative elements?
Yes, copper (Cu) is considered a representative element. Representative elements also called main-group elements, are the elements found in the s and p blocks of the periodic table. Copper is located in Group 11 and period 4 of the periodic table, making it a representative element.
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
Why do atoms of each element have 1 outer-level electron?
They don't. Of the main group, or representative elements, group 1 elements are the only ones whose atoms have only 1 electron in their outermost energy levels.
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.
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.
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.
Which group contains only radioactive elements?
The actinoids (formerly actinides) are all unstable metallic elements. The period 7 elements with atomic numbers from 89 (actinium, for which the group is named) through 103 comprise these elements. A link can be found below.
What group on the periodic table contains the fewest elements?
These groups are groups 3 to 12 (transition metals) containing each four chemical elements.
The group of elements that contains only alkaline earth metals is A 2 B 15 C 17 D 18?
A./2
What element is the only nonmetal in group 3 of the periodic table?
Group 3a (13) on the periodic table contains boron which is considered a metalloid. The other elements in the group are post-transition metals.
S orbital contains how many elements?
S orbital contains only 2 electrons and not elements.
