The backup software will automatically create a new folder inside the destination directory to run the backup job. Regular ZIP files can be opened by any archiver, but the encrypted ones cannot, so you should take that into consideration before making your choice. In addition to regular password protection, there is an optional encryption you can choose, or a combination of both. Toggle it, and if you want to protect the archive, set a password for it. Iperius Backup supports zip compression, though this option is not enabled by default. If you're worried about storage space, there is good news. Then comes the backup type, you can choose from Full and Incremental backups, along with the number of copies to be made. First up, you'll need to pick the directory where the files will be saved in. Hit the Next button near the bottom to proceed to the Destination settings. In case of folder backup, Iperius Backup has filters to exclude or include specific file types and sizes. When you click on one of the items, another window opens, and it prompts you to pick the folder or files that you'd like to save. The free version is limited to files and folders, so that's what we will be focusing on here. You may choose from Folders, Files, Drive Image, FTP Download, and more advanced options such as Hyper-V, SQL server, etc. Select the data that you want to backup from the Items tab. A new window pops-up, and it has its own ribbon UI. Click on the "Create new backup" button at the center of the screen, or the first icon on the Home tab, to get started. Iperius Backup runs in the background to run scheduled tasks, you can access it from the system tray. Therefore, there are various non-equivalent definitions of atomic radius.The program has a ribbon interface with a simple color palette. However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuum or free space. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus. It must be noted, atoms lack a well-defined outer boundary. The atomic radius of Rubidium atom is 220pm (covalent radius). Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Mass numbers of typical isotopes of Rubidium are 85 87. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z.įor stable elements, there is usually a variety of stable isotopes. Neutron number plus atomic number equals atomic mass number: N+Z=A. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10 -19 coulombs. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. Rubidium is a chemical element with atomic number 37 which means there are 37 protons in its nucleus. Atomic Number – Protons, Electrons and Neutrons in Rubidium
