Why do force of attraction between nucleus and electrons decrease in alkali metal as increase in size?
As alkali metals increase in size, the distance of the outermost electrons from the nucleus increases. The attraction between the electrons and the nucleus is electrostatic, and it is a fundamental property of electrostatic attractions that the attraction decreases with increasing distance between the attracting charges. Another way of describing this is that the attractive force is partially "screened" by the inner electrons between the outermost electrons and the nucleus.

Does the speed increase or decrease with the attraction between particles when changed from liquid to gas?
Yes, the speed increases when a liquid changes to a gas, And the attraction between particles also decreases. :) -Anouymous
Would the trend in atomic size cause an increase or a decrease in the attraction between the nucleus and the valence electron within the group as the atomic number increases?
Atomic size increases from top to bottom in a group due to increase in theshieldingeffect.As you go down the group shielding from core electrons increases (as more core electrons are added), therefore valence electrons experience weaker attraction forces from the nucleus and are located further away from it, resulting in an increase in size.If you move across a period the attraction between the nucleus and valence electrons increases because the number of protons and the number of valence electrons both go up whereas the number of core electrons stays the same (shielding decreases). In this case the size decreases.
What property has a trend similar to that of electronegativity?
Ionization energy has a trend similar to electronegativity. Both properties generally increase across a period from left to right and decrease down a group in the periodic table. This is because both involve the attraction between electrons and the nucleus of an atom.
Why sharing electrons causes atoms to bond together?
When electrons are shared between atoms, the nuclei of both atoms experience attraction towards the electrons and vice versa. At a certain distance, the attraction is maximal because the repulsion between the nuclei is small while the attraction of each nuclei to the electrons is strong. Thus, the atoms are held together by their attraction to the shared electrons.
Will the number of lines in an atoms spectra increase or decrease as the number of electrons in an atom increase?
As the number of electrons in an atom increase, the number of energy levels also increases, leading to more possible transitions between energy levels. This results in more spectral lines in an atom's spectrum as the number of electrons increases.

What can increase or decrease in atoms during ionic bonds?
During ionic bonds, atoms can gain or lose electrons to achieve a full outer shell, resulting in ions with a positive or negative charge. This process can increase or decrease the number of electrons in the outer shell, while the number of protons and neutrons in the nucleus remains constant. Electric attraction between oppositely charged ions leads to the formation of the ionic bond.
What would happen to two magnets if the distance between them increase?
As the distance between two magnets increases, the force of attraction or repulsion between them will decrease. This decrease is due to the weakening of the magnetic field as the distance between the magnets increases.
Why ionization energies of alkaline earth metals decrease from Be to Ba?
The decrease in ionization energies from Be to Ba in alkaline earth metals can be attributed to the increase in atomic size and the shielding effect of the inner electrons. As you move down the group, more energy levels are added, leading to increased distance between the nucleus and valence electrons, resulting in weaker attraction and lower ionization energies. The increased number of inner electrons also helps to shield the valence electrons from the attraction of the nucleus.

Ionization energy has a trend similar to electronegativity. Both properties generally increase across a period from left to right and decrease down a group in the periodic table. This is because both involve the attraction between electrons and the nucleus of an atom.
What is in the middle of decrease and increase?
The midpoint between decrease and increase is stability or equilibrium, where there is neither a decrease nor an increase occurring.
What factors contribute to the decrease in atomic radius as you move across a period on the periodic table?
The decrease in atomic radius as you move across a period on the periodic table is primarily due to increasing nuclear charge and the attraction between the positively charged nucleus and the negatively charged electrons. This stronger attraction pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
Does the gravitational attraction between earth and an asteroid decrease as the asteroid approaches earth?
The gravitational force (or attraction) between any two objects increases as the distance between them decreases. Thus, as an asteroid approaches Earth, the Earth's gravitational pull will increase as it gets nearer.
What is the strength of attraction between a nucleus and the outermost electrons?
The strength of attraction between a nucleus and the outermost electrons is determined by the electric charge of the nucleus (protons) and the distance between the nucleus and the electrons. This attraction is the basis for the force that holds atoms together and is essential for the stability of matter.
