Atomic Structure definitions

Question 1

Bohr’s Theory

Answer 1

Two equal and opposite forces act on the electron. Electrostatic- towards, centrifugal- away.

Question 2

Binding Force

Answer 2

the electrostatic attraction between the positive proton and negative electron.

Question 3

Binding energy

Answer 3

energy required to release an electron from its orbit (ionisation of an atom)

Question 4

Absolute potential

Answer 4

the work done in moving a unit of positive charge from infinity to that point

Question 5

potential difference

Answer 5

the work done in moving a unit positive charge in moving from one point to another

Question 6

volt (V)

Answer 6

1 volt of potential exists between two points if 1 joule of work is done in moving 1 coulomb of positive charge from one point to another
