It is possible, but it is not advisable. You need to enclose the column name in double quotes.

create table my_table ("MY COLUMN" number);

But note the warning in the documentation:

Note: Oracle does not recommend using quoted identifiers for database object names. These quoted identifiers are accepted by SQL*Plus, but they may not be valid when using other tools that manage database objects.

The name will be case-sensitive, and you wil have to enclose the name in double quotes every time you reference it:

select "MY COLUMN" from my_table;

So... don't, would be my advice...
