Generally when we move down the group on a periodic table the atomic radii increases as the valency electrons occupy higher levels due to the increasing quantum number. Hence the atomic radii increases down the group.
The ionic radii increases down the group because while we move down the group the elements gain electrons and form ions called anions as an additional electron occupies the orbital the ions get bigger in size. Hence the ionic radii increase.
Electronegativity is described as the ability to attract and bind with electrons and it is a qualitative property. It decreases as we move down the group because the distance between the valency electrons and the nucleus increases. Hence electronegativity decreases down the group.
Reactivity increases as we move down the group as the metals have the tendency to lose electron form its outer shell.
Therefore the answer is ionic radii increases.
I think the correct answer among the choices presented above is option A. An ore is rock that contains a mineral or metal with economic usefulness. Examples are copper ore, gold ore and iron ore. These ores are being extracted from the Earth by mining.

What's a tungsten atom
Is a chemical element with the symbol W and with an atomic number 74.
There is no question to your answers please list the question and I will be able to help.
Because the alkali metals are the group 1 metals, they have only 1 valence electron that they want to lose, and the halogens are the group 17 nonmetals, they want to gain 1 valence electron to become stable.
