Front

What is the electron dot structure for fluorine (F)?

Back

The electron dot structure for fluorine (F) shows 7 valence electrons, represented as dots around the symbol 'F'.

Front

What type of wave has a wavelength of approximately 10^-12 meters?

Back

Gamma rays are the type of wave with a wavelength of approximately 10^-12 meters.

Front

What type of orbital is represented by a spherical shape?

Back

The 's' orbital is represented by a spherical shape.

Front

What part of the electromagnetic spectrum can humans see?

Back

The visible spectrum is the part of the electromagnetic spectrum that humans can see.

Front

What type of wave has a frequency of approximately 10^8 hertz?

Back

X-rays have a frequency of approximately 10^8 hertz.

Front

Define valence electrons.

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases and vice versa.

Front

What is the visible spectrum range in nanometers?

Back

The visible spectrum ranges from approximately 400 to 700 nanometers.

Front

What is the shape of p orbitals?

Back

P orbitals have a dumbbell shape.

Front

What is the principle behind the photoelectric effect?

Back

The photoelectric effect demonstrates that light can eject electrons from a material when it has sufficient energy.
