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
What would be the name of the compound formed from the following elements Ba and Cl?
Barium chloride.
What is an element in group 2 at stp?
The group 2 of the periodic table of Mendeleev contain the following elements: Be, Mg, Ca, Sr, Ba, Ra.
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.
Would BA and O form a polar covalent bond?
The electronegativity difference between Ba (EN 0.89) and oxygen (EN 3.44) is high and you would expect bonds to be ionic. Barium oxide is ionic.

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)
What would be the name of the compound formed from the following elements Ba and Cl?
Barium chloride.
Arrange the following in order of increasing electronegativity Refer to the periodic table above?
cs, ca, co, c, cl ba be bi b br
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 an element in group 2 at stp?
The group 2 of the periodic table of Mendeleev contain the following elements: Be, Mg, Ca, Sr, Ba, Ra.
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.
What is the ionic character of barium oxide?
Barium Oxide = BaO Electronegativity (Pauling's) Ba = 0.89 O = 3.44 |0.89-3.44| = 2.55 Difference in electronegativity = 2.55 Percent Ionic Character ~ 79%
