There is no best column in Excel. All columns are the same. If you are referring to the best fit, then that is based on the widest entry in a column being used to set the width of the column.
It you select the blank cell under a column of numbers or a blank cell at the end of a row of numbers and hit the Autosum button it will enter the SUM function and select the cells above in the column, or to the left in a row. Pressing Alt and the = key will also do the same thing. If you select the column or the row with the numbers and click the button or do Alt and the = key, then it will also do the same.
Yes, they are the same. Powerpoint isn't for dealing with numbers generally, but you can set up tables of numbers and create charts from them, like you do in Excel.
No. It is not the same. the number of valence electrons are same for the elements in the same column (group).
VLOOKUP is a function of Microsoft Excel. You can use VLOOKUP to find a value in a table or list on an Excel sheet. It looks at a value in a column and finds the corresponding value in another column in the same row.
Cells in the same column must the be same width. You can make some higher than others, by adjusting their row size, but that is the only size difference there can be between cells in the same column. See the related question below for changing row and column sizes.
A column in Excel is the vertical (up and down) list of cells. You can think of columns the same as columns on a building that go from the top to bottom of a spreadsheet. The horizontal direction (e.g., left to right) is called a row.A row of numbers or data will go along from left to right, while a column will go from top to bottom (vertically).
Select data in a column to be sorted (including title row). Go to sort and filter (this will be in different places depending on version of excel), then custom sort, then select A-Z.Any other time you can use this to reverse from low to high (Z-A) or low to high (A-Z). It may also appear under sort -descending or ascending. This does the same thing.

In Excel, TAB would move your cursor to the next column in the same row.
You do not. Column width is consistent for all cells in column A. However, you can replicate the effect, by using multiple columns and merging cells.
Select cell formatting and change to text. After than, Excel will treat the numbers in a cell the same as any other text characters. Also, you will not be able to use that cell in a formula, because the formula will not recognize the characters as numbers.
