If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
The elements in the family Group 0 - Inert Gases (exc. Radon) will not usually combine with other substances, as this group is highly unreactive. Inert Gases; Helium Neon Argon Krypton Xenon (Radon)

Positive 1 charge
The valence of hydrogen is 1 and form the cation H+.
It would belong to group XVI, the group with oxygen.
The valence electrons of the element are very shielded. The valence electrons are far from the nucleus.
Li, or lithium, is the element most likely to lose electrons in a chemical bond. Lithium has 1 valence electron.
It indicates how many electrons are required to complete a full valence shell.

It is a "column" that represents a specific type of elements with the same type of characteristicas and also are likely to have the same valence electrons. e.g. the Noble Gases Family compose the "Group 8" because they all not react with any other element and their outer orbital has 8 valence electrons, which means is full, and that is also why the do not react!
The importance of valence electrons is that atoms in the same group ("groups" in the periodic table are the vertical columns- for example, nickel and platinum are in the tenth column; therefore, in the same group). Atoms of elements in the same group have the same number of valence electrons, so they have similar properties. Hope that helped with your homework! ;D

"Element-logy" likely refers to the study of elements, which belong to the periodic table of elements. Elements are substances that cannot be broken down into simpler components and are represented by a unique chemical symbol.
Elements in the 1st group have 1 valence electron. So they are likely to donate 1 electron to get more stable. potassium, rubidium and cesium are likely to donate 1 electron.
