What else can I help you with?
Is helium a metal and a nonmetal?
No, helium is not both a metal and a nonmetal. The element helium (He), along with its cousins in Group 18 of the periodic table of the elements, is a monatomic nonmetal.
How does reactivity correlate to each elements location on the periodic table?
Reactivity is associated with position. Chemical properties of element can be determined from its position.
What does grouping on the periodic table of elements have to do with reactivity?
Grouping describes the behavior of elements. Different groups have different properties.
What trends were seen in Mendeleev?
In Mendeleev's periodic table, several key trends were observed, including the periodicity of element properties such as atomic mass, reactivity, and valence. He arranged elements in order of increasing atomic mass, which revealed recurring patterns in their chemical behavior. Mendeleev also left gaps for undiscovered elements, predicting their properties based on the trends he observed, which demonstrated the predictive power of his periodic arrangement. This laid the groundwork for the modern periodic table, where elements are organized by atomic number.
What is the group number and name of the most active nonmetal?
The most active nonmetal is fluorine, which is located in Group 17 of the periodic table, also known as the halogens. Fluorine is highly reactive due to its strong electronegativity and small atomic radius, allowing it to easily attract electrons from other elements. Its reactivity makes it the most electronegative element, contributing to its status as the most active nonmetal.
What properties of these elements are indicated by their positions in the periodic table?
For example metal or nonmetal character, radioactivty, atomic weight, reactivity.
Is nitrogen a metal nonmetal or a metalloid?
Nitrogen is a nonmetal. It is a gaseous element found in Group 15 of the periodic table and is known for its low reactivity and tendency to form covalent bonds.
Is alkali a nonmetal?
The elements in the alkali column of the periodic table are metals.
Why isn't water a nonmetal on the periodic table?
Water isn't on the periodic table as it is a compound and only elements are on the periodic table
Are all elements on the left side of the periodic table a nonmetal?
no there all metal
What are Bromine chlorine and fluorine examples of .?
Bromine, chlorine, and fluorine are examples of halogens, which are a group of reactive nonmetal elements located in group 17 of the periodic table. They are known for their high reactivity and ability to form salts with metals.
Is hydrogen a metal or nonmetal or feeling does it belong to?
Hydrogen is a nonmetal. It is placed in the upper left corner of the periodic table, making it part of the nonmetal group of elements.
Is helium a metal and a nonmetal?
No, helium is not both a metal and a nonmetal. The element helium (He), along with its cousins in Group 18 of the periodic table of the elements, is a monatomic nonmetal.
How is This nonmetal group contains chorine and iodine?
The nonmetal group containing chlorine and iodine is the halogen group, which is located in group 17 of the periodic table. Halogens have high reactivity and readily form compounds with other elements. Chlorine and iodine, along with fluorine and bromine, are known members of this group.
How can you show that carbon is not a metal?
By looking at the periodic table of the elements. Carbon is listed as a nonmetal.
Is reactivity indicated by the position of the element?
Reactivity of an element is not directly indicated by its position on the periodic table. However, general trends can be observed - for example, elements in group 1 and group 17 tend to be highly reactive due to their tendency to gain or lose electrons, respectively.
How does reactivity correlate to each elements location on the periodic table?
Reactivity is associated with position. Chemical properties of element can be determined from its position.
