Answer:
Cl EN < O EN < F EN
Explanation:
Electronegativity is a periodic property that indicates the tendency of an atom to attract electrons when combined with another element. It is very useful for predicting the type of bonding of compounds, so it is not possible to talk about electronegativity in elements in a fundamental state.
In the periodic table the electronegativity increases diagonally and the values were established in the so-called Pauling scale.
It is expected that elements with high electron affinity and high ionization energy possess considered electronegativity, so the group of nonmetals have high electronegativity, in fact flour is the most electronegative element
Answer:
Covalent Bond
Explanation:
Because of the unequal sharing of electrons, a covalent bond exists.
The freezing temperature at a normal sea level air pressure is negative 78.5 degrees.
% by mass = (mass solute/mass solution)*100%
mass of the solute = 54.7 g
mass of the solution = mass solute + mass solvent=54.7+500=554.7 g
% by mass = (54.7/554.7)*100%≈0.0986*100% = 9.86%
