2.2- Atomic Attraction

Question 1

Which charges attract each other?

Answer 1

positively and negatively charged elements

Question 2

Which charges repel each other?

Answer 2

positively and positively charged elements

negatively and negatively charges elements

(same charged elements)

Question 3

What is the relationship between coulombic attraction and the charge of elements?

Answer 3

the stronger the charge of the elements, the stronger the coulombic attraction

Question 4

What is the relationship between coulombic attraction and distance between the elements?

Answer 4

the more distance between the elements, the weaker the coulombic attraction

the less distance between the elements, the stronger the coulombic attraction

Question 5

What element has the highest level of electronegativity?

Answer 5

Electronegativity increases from bottom to top in groups, and increases from left to right across periods, thus making Flourine the element with the highest level of electronegativity

Question 6

Which atom has the weakest attraction to its valence electrons?

Answer 6

Sulfur:

The radius of a sulfur atom is about 60% larger than that of an oxygen atom

Question 7

Which atom has the strongest attraction to its valence electrons?

Answer 7

Flourine:

Fluorine is the most electronegative element because it has 5 electrons in its 2p shell

Question 8

Define direct relationship in Coulomb’s Law

Answer 8

if either variable increases, the force will also increase by the same magnitude

Question 9

Define indirect relationship in Coulomb’s Law

Answer 9

as distance increases, the force decreases by that magnitude squared
