Explanation:

Although it might seem counterintuitive, atomic radius go decrease indigenous left to ideal on the periodic table. The reason for this is since the included positive fee in the nucleus reasons the elctrons to it is in pulled more strongly towards the center, which decreases the atom radius.

Explanation:

Electronegativity values become greater together you relocate up and to the ideal on the periodic table. Of the four atoms listed, sulfur is the highest possible up and farthest come the right, giving it the best electronegativity.

Explanation:

Ionization energy is the amount of energy that an atom in the floor state have to absorb come emit an electron. ~ above ionization, a cation is formed. Ionization power increases from bottom to height within a group, and from left to right within a row of the regular table i beg your pardon is the opposite tendency that atom radius follows. Introduce to the periodic table, we have the right to see the of these group VII elements, fluorine has actually the highest possible ionization energy.


Explanation:

All of these atoms are in group VII. Within a group, atomic radii rise from top to bottom as result of the increased variety of electron shells.


Explanation:

Ionization energy is the amount of energy that an atom in the ground state must absorb come emit an electron. Upon ionization, a cation is formed. Ionization power increases native bottom to top within a group and from left come right across a duration in the periodic table i beg your pardon is the opposite trend that atomic radius follows. Introduce to the periodic table, it can be watched that helium has actually the highest ionization energy of those in the list. 


As you progression from left to best along the routine table, the electronegativity __________ and also the atomic size __________.


Explanation:

There are four main regular trends: electronegativity, atomic size, ionization energy, and also electron affinity. Electronegativity measures how conveniently an atom can entice an electron to kind a covalent bond, atomic size (as the name implies) measures the dimension of the atom, ionization energy measures the amount of power required to remove an electron, and electron affinity measure up the amount of energy released upon absorption of an electron. Electronegativity increases as us go towards the top right of the periodic table (Fluorine has actually the greatest electronegativity), atom size increases as us go in the direction of the bottom left, ionization energy increases as we go towards optimal right, and also electron affinity increases as us go towards peak right.

This means that together we walk left come right, electronegativity, ionization energy and electron affinity will certainly increase.
