What else can I help you with?
Which of the following lists four elements from greatest electronegativity to least electronegativity Fe Co Ni Zn Ba Fe Al He Cl Si Mg Na Rn Ge Si Ar?
Fluorine has the most electronegative element, Cl and Br
Could Ba and O form a covalent bond?
Ba and O are unlikely to form a covalent bond because they have a large electronegativity difference. Ba is a metal with a low electronegativity, while O is a nonmetal with a high electronegativity. This large electronegativity difference makes it more favorable for them to form an ionic bond rather than a covalent bond.
What would be the name of the compound formed from the following elements Ba and Cl?
The compound formed from Ba and Cl would be named barium chloride.
What bond does the element Ba-O have covalent or ionic?
You should check the electronegativity values of Ba and O. The difference between these two will tell you what type of bond you are dealing with. A table of these values are found in a standard chemistry textbook. However, as a rule of thumb, alkali and earth-alkali metals such as Ba, Ce, Na etc. very often form ionic bonds. However, you should NEVER refer to something like Ba-O or NaCl or H2O as an element! Elements are the fundamental building blocks, that is, only one element, like Fe (iron). Two or more elements form a chemical substance.
How does the bond that forms between Ba and Br demonstrate that the boundaries between bond types as determined by electronegativity differences are not clear cut?
The bond between Ba and Br demonstrates that the boundaries between bond types are not clear cut because Ba and Br have a significant electronegativity difference, indicating an ionic bond. However, due to the large size of Ba and the polarizability of Br, some covalent character can also be present in the bond, blurring the distinction between purely ionic and covalent bonds. This shows that the electronegativity difference alone is not always sufficient to classify a bond type definitively.

Arrange the following in order of increasing electronegativity Refer to the periodic table above?
cs, ca, co, c, cl ba be bi b br
Arrange the following elements in order of increasing electronegativity N Na Ni K P?
The electronegativity from least to highest : Ba, Be, Bi, B, Br The electronegativity of an element is a measurement of how its atoms attract electrons. This is based on the atomic weight (width of the atomic nucleus) and the distance of its valence electrons from the nucleus. As displayed on the Periodic Table, elements generally increase in electronegativity as you move across (left to right), and decrease as you go down the table. (Only aluminum does not follow this in this set of elements.) (see related link)

Rank the following elements in order of increasing first ionization energy C Ne Sr Mg Be?
Ne (Highest First Ionization Energy) C Be Mg Sr (Lowest First Ionization Energy)
Is BaO ionic or molecular?
No. One way to tell is that Ba and O are on opposite sides of the periodic table, and Ba is a metal and O is a nonmetal. We can also determine the difference in electronegativity. A difference of >1.6 is generally considered as ionic. The electronegativity of Ba is 0.89 and of O is 3.44. 3.44 - 0.89 = 2.55, so the bond is ionic.

What is the trend in electronegativity down group 2from Be to Ba?
The electronegativity decreases going down Group 2 beryllium:1.5; magnesium:1.2; calcium: 1.0; strontium:1.0; barium:0.9

How barium reacts with other elements?
Ba looses its two electrons to form Ba 2+ ion and then it reacts with other elements to form compounds.
How does the bond that forms between Ba and Br demonstrate that the boundaries between bond types as determined by electronegativity differences are not clear cut?
The bond between Ba and Br demonstrates that the boundaries between bond types are not clear cut because Ba and Br have a significant electronegativity difference, indicating an ionic bond.

This shows that the electronegativity difference alone is not always sufficient to classify a bond type definitively.
Are the elements ba and ca metals or nonmetals?
Barium (Ba) and calcium (Ca) are both metals, belonging to alkaline earth metals or group 2.
