Which best explains why ionization energy tends to decrease from the top to the bottom of a group? Electrons get farther from the nucleus. a cation that has a smaller radius than the atom. In which orbitals would the valence electrons for selenium (Se) be placed?
Why does ionization energy increase across a period and decrease down a group?
Ionization energy (IE) is the energy required to remove the highest-energy electron from a neutral atom. In general, ionization energy increases across a period and decreases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.

Which explains the change in ionization energy that occurs between removing the first and second electrons from an atom?
Which explains the change in ionization energy that occurs between removing the first and second electrons from an atom? –The ionization energy decreases because the ratio of the protons to electrons increases.
How do ionic bonds affect the properties of ionic compounds quizlet?
How do ionic bonds affect the properties of ionic compounds? The bonds prevent ions from moving throughout the crystal, so a solid ionic compound is a poor conductor.
Why ionization energy decreases down a group?
Going down a group, the ionisation energy decreases. This is due to the shielding or screen effect of the outer electrons from the nucleus and so the attraction is weaker and they are more easily removed.
Why does ionization energy decrease down a group quizlet?
Why does ionization energy decrease as you move down the periodic table? Because outer electron are further away from the nucleus as you go down a group, they feel less pull from the nucleus, so they are easier to remove.
Why does the ionization energy increases across a period?
On the periodic table, first ionization energy generally increases as you move left to right across a period. This is due to increasing nuclear charge, which results in the outermost electron being more strongly bound to the nucleus.
How do ionic bonds affect the properties of ionic compounds?
Ionic bond is a very strong bond and very hard to break, which gives the ionic compound very high melting and boiling points. Ionic bond also makes a compound conductor, as ions are involved in making the compound.
How do ionic bonds affect the properties of ionic compounds the bonds weakly hold ions together increasing the melting point?
How do ionic bonds affect the properties of ionic compounds? The bonds weakly hold ions together, increasing the melting point. The bonds strongly hold ions together, reducing the boiling point. The bonds prevent ions from moving throughout the crystal, so a solid ionic compound is a poor conductor.
How do ionic bonds affect the properties?
How do ionic bonds affect the properties of ionic compounds? The bonds prevent electrons from moving throughout the crystal, so a solid ionic compound is a poor conductor.
Why does first ionization energy decrease from top to bottom?
The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Since the outermost electrons are further away, they are less strongly attracted by the nucleus, and are easier to remove, corresponding to a lower value for the first ionization energy.
