You forgot one...and that happens to be the answer---> Accuracy
Answer:
2) Their kinetic energy increases.
Explanation:
The particles have more kinetic energy because they move around more when they are a liquid.
<span>iron has 26 protons and 30 neutrons are in the nucleus</span>
YES, the arrangement of elements on the periodic table relate to their chemical properties
Explanation:
As you move across a period, the atomic radius decreases due to the increase in atomic mass and hence attraction of orbitals by the increasingly positive nucleus. Therefore, the atoms become increasingly harder to lose electrons (due to increasing ionization energy) in their valence shell and more likely to take up electrons in chemical reactions.
The lower you go down the periodic table the higher the reactivity of the atoms. This is because they have more electron shells and the valence electrons are shielded from the atomic nuclei by underlying orbitals. This means that the valence electrons are easily lost (ionization energy is low) and can, therefore, react fast in chemical reactions.
