Bonds

Question 1

What is a polar covalent bond?

Answer 1

A bond in which electrons are unequally shared, seen in atoms with differences in electronegativity

Question 2

What is a non-polar covalent bond?

Answer 2

A bond in which electrons are equally shared between atoms, seen in atoms with similar electronegativity

Question 3

What is an ionic bond?

Answer 3

A bond in which an electron is transferred (or stolen) from one atom to another. The atoms (now ions) are held together by attraction between opposite charges.

Question 4

What is a cation

Answer 4

An ion with a positive charge. Occurs when an electron is transferred to another atom.

Question 5

What is an anion

Answer 5

An ion that took a transferred electron from another atom through ionic bonding, and has a negative charge because of the extra electron

Question 6

What is electronegativity?

Answer 6

The tendency of an atom to attract a bonding pair of electrons. These atoms steal electrons when bonding ionic-ly

Question 7

How many electrons fit in the first electron layer?

Answer 7

2

Question 8

How many electrons fit in the outer valence shell?

Answer 8

8

Question 9

What is a covalent bond?

Answer 9

A bond in which electrons are shared

Question 10

What is a hydrogen bond?

Answer 10

Weak attraction between a slightly positive hydrogen atom and a slight negative atom such as oxygen or fluorine.

Question 11

What is the relative strength of known bonds

Answer 11

Covalent>ionic>hydrogen
