As the speed of a particle increases, does its associated wavelenght increase or decrease
Zina [86]

The de Broglie hypothesis proposed that all particles have wave-like properties, with the wavelength being inversely proportional to the velocity of the particle.


Therefore as the velocity (speed in this question) increases, the wavelength *decreases*.

What happens to the composition of an atom to cause it to become positively or negatively charged?
cupoosta [38]
<span>The addition and subtraction of negatively charged electrons can easily change an atom’s charge, because they perpetually spin in valence shells outside the nucleus. It is easier for a neighboring atom to share or steal an electron rather than a positively charged proton, which is found in the nucleus. It requires a strong energy input to split a proton free from other protons and neutrons. thus, the atoms lose or gain electrons from neighboring ones and become what is known as "ions". Hope it helped!</span>
