How is it possible that the elements get smaller as you move left to right across a period on thetable?
Each element from left to right gains a proton, which increases the pull of the nucleus on it's electrons. Each element also gains an electron, but the electrons are added to the same or a lower energy level..only when you go down a group do the number of energy levels increase. This pull of the nucleus causes the atomic radius to decrease because the electrons are pulled in tighter by the stronger nucleus. As you go down, atoms get bigger because of added energy levels. Energy levels on the outside are shielded from the nucleus by electrons on inner levels, so they range further away from the nucleus.
Why atomic radii decrease as you move left to right?
The farther right you go along a periodic table, the more protons and elctectrons the atoms have. As the number of protons and electrons increases, the attraction between them increases, which draws the electrons closer to the nucleus (protons and neutrons), thus decreasing the atomic radii.
Does atomic radius have a bigger atomic number as you go to the right of the periodic table?
Yes. Generally atomic radii turn to decrease as you move across the periodic table from left to right. this is because the nuclear charge increases as you move right across the period but the electron screening remains the same. consequently, the protons in the nucleus has a greater pull on the electrons.
Does shielding effect different in a period?
Yes, shielding effect varies in different periods of the periodic table. It generally increases from left to right across a period due to the increase in nuclear charge, which results in a stronger pull on the electrons in the inner shells towards the nucleus. As a result, the outer electrons feel less of the nuclear charge, leading to a stronger shielding effect.
What happens to the atomic radius as you go across a period?
It decreases as you move from left to right because there is an increase in positive charge in the nucleus as you go from left-to-right. Each time you go over an element it has one more electron and proton added to the principal energy level, so the nucleus pull increases and it holds the valence electron in tighter.
What happens to the pull on the electrons in the Periodic Table?
The pull on electrons in the Periodic Table increases from left to right across a period due to increasing effective nuclear charge. From top to bottom within a group, there is less pull on the electrons as electrons are added to higher energy levels further away from the nucleus.
How do you drive a horse?
Kiss to go faster. Pull back to stop. Pull on the right rein to go right. Pull on the left rein to go left.
When looking across a period of the periodic table from left to right when happens to the atomic number and electronegativity?
As you move across a period from left to right in the periodic table, the atomic number of the elements increases by one with each element. Electronegativity also increases across a period from left to right due to the increasing nuclear charge and decreasing atomic radius, which results in stronger pull on electrons.
Why does the ionization energy increases as you go from left to right across a period?
because the more valence electrons a element has, the more it wants to become a noble gas. The pull is stronger because it is trying to get other electrons.
What happens to electronegativity as you go across a period?
Electronegativity increases as you go across a period from left to right due to a stronger pull on electrons by the increasing positive charge of the nucleus. This results in atoms becoming more effective at attracting electrons.
Why does atomic radii decrease moving left to right across a period?
Atomic radii decrease moving left to right across a period because as you move from left to right, the number of protons in the nucleus increases, leading to a greater nuclear pull on the electrons. This increased nuclear attraction pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
Explain why atomic radius generally decreases as you go left to right across a row on the periodic table?
As you move from left to right across the Periodic Table, the number of protons in the nucleus of each successive atom increases by one. Correspondingly, the number of electrons also increases by one. However, if the elements in question are on the same energy level, the added ''pull" of the protons serves to pull the orbiting electrons closer to the nucleus, thus causing the radius of the atom to become smalller as you move from left to right. As you move down the periodic table, atoms get larger. As you move down the table, you continue to add protons and electrons. However, you also add energy levels and, in so doing, the orbiting (and available) electrons get further from the nucleus and the pull of the protons. It is the distance between protons and available electrons that allows the radius of the atoms to get larger. It also explains why reactivity increases as you go down the table. The pull of protons on the available electrons of small atoms is much greater than the pull of protons on the available electrons of large atoms, so the large atoms release their electrons much more readily.
How does the atomic radius change from the left to the right horizontal row in the periodic table?
The atomic radius decreases from left to right across a period in the periodic table. This is due to the increasing number of protons in the nucleus, which pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
What happens to the pull of gravity when the sun and moon at right angles?
The Gravitational pull on the oceans is Partially canceled out by the suns Gravitational pull.
