Why are group1 and 7 found as compounds?
Group 1 elements have very low electronegativies and group 7 elements have very high electronegativities, so that both are reactive with almost every other element, the group 1 elements by donating electrons and the group 7 elements by accepting electrons.
Does covalent compounds have a high or low electronegativity?
In comparison with ionic bonds, the difference in electronegativities of elements in a covalent bond have a lower difference in electronegativities. A covalent bond occurs between two nonmetals that have a difference in electronegativities that is 1.7 or less. Usually an ionic bond has a difference in electronegativities that is greater than 1.7, but not always.
Why group 1 and group 2 elements do not occur free in nature?
Group 1 and group 2 elements are reactive metals and react readily with water. They also react readily at high temperatures with oxygen. Over the millenia any free deposits would react to form compounds.
How is electronegativity related to metallic character?
Electronegativity and metallic character are inversely related - elements with high electronegativities tend to have low metallic character, and vice versa. Electronegativity measures an element's ability to attract and bind electrons, while metallic character refers to an element's tendency to lose electrons easily and form cations. Therefore, elements with high electronegativities typically have low metallic character because they hold onto their electrons more strongly.
In which group are the elements always linked with others to form compounds?
The elements in the group known as the halogens (Group 17) are always linked with others to form compounds due to their high reactivity and tendency to gain an electron to achieve a stable configuration. This group includes elements like chlorine, fluorine, and iodine.

Based on its location on the periodic table which element would be most likely form a negative?
Elements located on the right side of the periodic table, particularly the nonmetals in Group 17 (the halogens), are most likely to form negative ions. These elements, such as fluorine and chlorine, have high electronegativities and readily gain electrons to achieve a stable electron configuration, forming anions. Additionally, elements in Group 16, like oxygen and sulfur, can also form negative ions by gaining electrons.

Electronegativity and metallic character are inversely related - elements with high electronegativities tend to have low metallic character, and vice versa.

Therefore, elements with high electronegativities typically have low metallic character because they hold onto their electrons more strongly.
What Elements on the left side of the table are classified as what type of elements?
Group 1 Elements (elements in the first group [column]) are classed as Alkali Metals. Group 2 Elements (elements in the second group [column]) are classed as Alkaline Earth Metals. All elements not in a representative group are classed as Transition Metals. Group 3 Elements (elements in the third full group [coulumn]) are classed as Earth Metals
Which group includes the halogens and which elements are in that group?
The halogens group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. These elements are located in group 17 (Group VIIA) of the periodic table and are known for their high reactivity and tendency to form salts when they react with metals.
What are the charateristic properties of noble glass?
Noble gases are colorless, odorless, and tasteless elements that are non-reactive under normal conditions. They have high ionization energies and low electronegativities, making them stable and unreactive. These gases are found in Group 18 of the periodic table and include helium, neon, argon, krypton, xenon, and radon.
Why some elements do not have chemical bonds?
Elements such as helium and neon are noble gases and ave a full set of 8 electrons in their outer shell. this means they wont form covalent bonds. they also have high electronegativities so they wont react with acids or form ionic compounds.
In which group are the elements always linked with others to form compounds?
The elements in the group known as the halogens (Group 17) are always linked with others to form compounds due to their high reactivity and tendency to gain an electron to achieve a stable configuration. This group includes elements like chlorine, fluorine, and iodine.
What group of nonmetals are the most reactive and why are they the most reactive?
The halogens, periodic table column 17, are the most reactive nonmetals, because they have the highest electronegativities and therefore can strongly attract electrons from almost any other elements.
Which group of elements form cations?
what are true about cationA.Metals are not likely to form cations.B.Cations are always smaller than the neutral form of the element.C.Cation size decreases as you go down a group.D.All cations are larger than any anion.E.Cations cannot form in nature.
