Based on the trend, an electron will be most strongly attracted to Cl, chlorine. The correct option is D.
Electronegativity is a property of an element which show the tendency of that element to accept electrons from other element. When an atom accept electrons, it gets a negative charge, the charge increase with the increase of accepting number of electrons.
Chlorine is a gas and is highly acidic. It has the highest electronegativity because it has the highest tendency to form a covalent bond with other element.
Chlorine has seven electrons in its outer shell, and it needs only one electron to complete its octave equal to the noble gas configuration.
Thus, the correct option is D. Cl.

Answer:
Cl
Explanation:
The electronegativity follow the trend that the higher the element is the more electronegative he is, for exemplo, in F, Cl and Br are all from the same group, 17A, put F has the lowest atomic number, followed by Cl and Br is the last, because of that F is the more electronegative from them, followed for Cl and Br is the element with lowest electronegativity.
And this trend also says that the element that are on the right of the table will have the higher electronegativity, for exemplo F, K and Be, all of the will have electron on the second band of valence but F is for the group 17A, K is from the 1A and Be is form the 2A. Because of that F is, one again, the one with the highest electronegativity followed by Be and K is the one with the lowest electronegativity of them all.

Answer:
1 gram molecular mass of this compound = 20
Explanation:
Gram Molecular Mass is the mass of a chemical that is obtained by the number of grams in the chemical determined by the masses obtained from the periodic table and the number of mols determined from the Chemical formula.
That's quite a mouthful. Here's what it means in plain language.
Find the Gram molecular mass of C2H6
The periodic table tells us that 1 mol of C2H6 has
2 mols of Carbon which is 2*C or 2 * 12 = 24 and
6 mols of Hydrogen which is 6*H or 6*1 = 6
The gram molecular mass is 6 + 24 = 30
Your question doesn't require all that background.
5 gram molecular masses = 100 grams Given
1 gram molecular mass = x
5/1 = 100/x Cross multiply
5x = 100 Divide by 5
x = 100 / 5
x = 20
The gram molecular mass of a compound whose 5 moles has a mass of 100 grams would be 20 grams per mole.
The gram molecular mass of a substance is simply the mass (in gram) of 1 mole of the same substance. In other words, the gram molecular mass of a substance is also the same as the molar mass of the substance.
In this case, 5 moles of the substance weigh 100 grams
Therefore, 1 mole of the same substance would weigh:
1 x 100/5 = 20 grams
