Why electropositivity first increases from boron to aluminium and then decreasesfrom aluminium to thallium in group 3?
The increase in electropositivity from boron to aluminum is due to the decrease in ionization energy, making it easier for aluminum to lose electrons. However, from aluminum to thallium, the increase in effective nuclear charge outweighs the increase in atomic size, making it harder for thallium to lose electrons, thus decreasing electropositivity.
Why would a linear accelerator have no effect on a neutron?
A linear accelerator works by having a magnet at the end of the accelerator. If the particle is neutral then it will not be attracted to the magnet and therefore nothing will happen, as in the case of a neutron.
How does an atom get neutrally charged?
A neutral atom has an equal balance of Protons and Electrons. Protons are positively charged whilst Electrons being opposites are negatively charged. To change a neutral atom to a positively-charged atom can be done by either removing an Electron from the atom, or by adding a Proton. Removing 1electron would make the number of Protons > number of Electrons by 1 making the charge on the neutral atom change to +1. Adding a Proton, the same effect occurs. To make a neutal atom negatively-charged simply do the reverse and make the Number of electrons > number of protons.
Electrons ejected in the photoelectric effect are called?
Photo electrons. So current due to these photo electrons is named as photo electric current.
What effect does hydrofluoric acid have on gold?
Hydrogen Fluoride (HF) will react with the surface of the aluminum and convert the aluminum oxide to aluminum fluoride. Water (H2O) is produced as a byproduct. In this way the HF works as a polishing agent to make the aluminum "shiny" again. Depending on the concentrationof the HF, the contact time, and temperature, the HF can continue to react with the aluminum and corrode it.
Which would have more of an affect on the mass of an aluminum atom removing ten electrons or one neutron?
Removing ten electrons would have a larger effect on the mass of an aluminum atom than removing one neutron. Electrons have very little mass compared to protons and neutrons, so removing ten electrons would significantly decrease the mass of the atom. Neutrons contribute roughly the same mass as protons, so removing one neutron would have a smaller impact on the overall mass of the atom.
What would have more of an effect on the mass of an alumnium atom removing 10 electrons or 1 neutron?
ten electrons. If u look on the worksheet it says that neutrons are particles with no charge
Which type of energy works by removing electrons from atoms to produce electricity?
solar
What characteristic of copper and aluminum causes the to be good conductors what is the effect?
They are both metals. The effect is that copper is more safer than aluminum. From Leah :)

What characteristic of copper and aluminum causes them to be good conductors what is the effect of this?
Copper and aluminum have high electrical conductivity due to their structure of free electrons that can move easily. This allows electric current to flow through them with minimal resistance, resulting in efficient transmission of electricity in wires and cables.
The first rotation of neutron stars is a consequence of what effect?
The conservation of angular momentum.

What effect on removing prey have on predators?
they leave or the die out
What are the differences between the photoelectric effect and the Compton effect in terms of their interactions with matter and the behavior of photons?
The photoelectric effect involves the ejection of electrons from a material when photons of sufficient energy are absorbed, while the Compton effect involves the scattering of photons by free electrons in a material, resulting in a change in the photon's wavelength. In the photoelectric effect, photons interact with electrons in the material, leading to the ejection of electrons, while in the Compton effect, photons collide with free electrons, causing them to scatter and change direction.
What effect does vinegar have on aluminum?
Vinegar can cause aluminum to corrode or oxidize, leading to the formation of a dull, rough surface on the metal.
