The elements in Group 2 of the Periodic Table are:
Beryllium
Magnesium
Calcium
Strontium
Barium
Radium
The total number of element combinations depends on the number of elements that are being combined. For example, if you are combining 2 elements, there would be a total of 2 combinations (element 1 + element 2). If you are combining 3 elements, there would be a total of 6 combinations (element 1 + element 2, element 1 + element 3, element 2 + element 3). The formula to calculate the number of combinations is n(n-1)/2, where n is the number of elements being combined.
Helium (He) is the element that is number 2 on the Periodic Table of Elements. It has an atomic number of 2 and is a noble gas.
Elements are pretty much defined by the number of protons in the nucleus. This number (the atomic number) defines the element. All the different elements have different numbers of protons in their nucleus.

The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.

For example, if you are combining 2 elements, there would be a total of 2 combinations (element 1 + element 2).

It is 2. Compounds consist of at least 2 elements.
No, the number of protons is what determines what element it is
An oxidation number of 2 means the element has lost or gained 2 electrons in a chemical compound. The oxidation number is a measure of the element's ability to combine with other elements.
The valence of an element in a chemical compound can be determined by looking at the group number of the element on the periodic table. The group number indicates the number of valence electrons an element has. For example, elements in group 1 have a valence of 1, elements in group 2 have a valence of 2, and so on. The valence of an element is important in understanding how it will react with other elements to form compounds.
Elements are pretty much defined by the number of protons in the nucleus. This number (the atomic number) defines the element. All the different elements have different numbers of protons in their nucleus.
To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
