Hydrogen is a unique element of the Periodic Table. Due to its
similarities in properties it can be placed at the top of group 1A
or 4A or 7A.

Hydrogen, which is properly a member of the periodic column. If the properties of hydrogen are considered too little like those of the other elements in the this column, the alkali metals, so that only the latter are considered members of column IA, then the answer would be lithium.
First off, there is no "salt" on the periodic table of the elements. Salt is a compound. However, you may be talking about "sodium". If that's the case, sodium is NOT in the same column as oxygen in the periodic table. Sodium is in the first column while oxygen is in the sixteenth column.
They are all in the same column in the periodic table which means that they only have one electron and react easily with other elements.
Each vertical column in the periodic table is group.There are 18 groups in periodic table.Seventeenth group belongs to halogens.
Iodine is in the 17th column (towards the right end of the periodic table) and is therefore a halogen. Halogens occupy the 17th column. Metals general occupy the left and center of the periodic table, discluding hydrogen. Iodine, therefore, is highly reactive and likely to become an anion whereas metals generally become cations.
It is at the very top left column. Hydrogen is the first element.

Hydrogen is a non-metal; it's in group VII
==Yes== Hydrogen, a gas, is found on the left side of the periodic table. And it depends on which periodic table you look at. The standard 18 column ones have hydrogen on the left, but, a geologists' periodic table may have more (sorry, I'm not a geologist, I just know there is such a thing). But I think you mean the everyday periodic table... So yes, hydrogen.
Francium has the largest nucleus in the hydrogen group; it's always the atom in the lowest row (highest period number) of any column in a normal periodic table that has the largest nucleus in that column.

Alkaline metals and hydrogen, all the elements in the first column of the Periodic Table.
The Alkali Metals are the first column of the periodic table, except for Hydrogen.
All of the alkali metals, periodic column 1 excluding hydrogen in a wide form periodic table, and all but the two lightest alkaline earth elements, periodic table column 2 excluding beryllium and magnesium, have the reactivity specified by the question.
Beryllium is in column 2 of a wide form periodic table and column II(A) of a narrow form periodic table.
