M3 part 2

Question 1

The model aims to explain the stability of the atom:

Answer 1

Bohr Model of the Atom

Question 2

characteristics of Bohr Model of the Atom

Answer 2

• presence of fixed circular orbits or energy levels
• ground state will have the electrons in constant energy
• light energy can be absorbed and be emitted by electrons

Question 3

The orbits in Bohr Model are

Answer 3

quantized energy levels

Question 4

There is a specific
amount of energy
required for each
distance and this energy _________ when going
farther away from the
nucleus.

Answer 4

increases

Question 5

characteristics of electron in bohr model

Answer 5

● Electrons are originally at its ground state.
● Electrons can absorb energy and will become excited.
Electrons jump to higher energy levels when excited.
● Electrons can then relax and go back to its ground state.
This will give off energy that has a specific wavelength and
color.

Question 6

The emitted light from
relaxation can be
detected resulting to

Answer 6

spectral lines

Question 7

These will give the
distinct color that we
see when metals are
heated or when light is
being reflected by
matter

Answer 7

spectral lines

Question 8

The Balmer series of spectral lines was able to identify the
presence of orbitals. The spectroscopic data were described

Answer 8

Erwin Schrödinger (Cloud model)

Question 9

spectroscopic data

Answer 9

○ sharp – s orbital
○ principal – p orbital
○ diffused – d orbital
○ fundamental – f orbital
