Glossary
- block: The periodic table can be divided into blocks denoting which sublevel is in the process of being filled.
- period: Each horizontal row of the seven rows of the periodic table.
- sublevel: Electron orbitals s, p, d or f.
What is group 7A on the periodic table?
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The name “halogen” means “salt former”, derived from the Greek words halo- (“salt”) and -gen (“formation”).
What are the groups on the periodic table called?
The groups in the Periodic table are also called Families because;. The elements lying in the same group have same number of valence electrons, which results in their similar properties (like similar habits of all the family members.)
What are the periods and groups in the periodic table?
Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period. Elements in a group share a common number of valence electrons.
How do you memorize the periodic table?
- Exercise to clear your head.
- Write down what needs to be memorized over and over.
- Do yoga.
- Study or practice in the afternoon.
- Relate new things to what you already know.
- Stay away from multitasking.
What are the 4 sublevels of the periodic table?
Recall that the four different sublevels each consist of a different number of orbitals. The s sublevel has one orbital, the p sublevel has three orbitals, the d sublevel has five orbitals, and the f sublevel has seven orbitals.
What is a sublevel?
Definition of sublevel : a level that is lower than or subordinate to another level a sublevel garage The 60 words were divided into nine separate groups based on grade levels and sublevels.—
How do you find the sublevels on the periodic table?
The Periodic Table can be divided into s, d, p, and f sublevel blocks. For elements in the s sublevel block, all valence electrons are found in s orbitals. For elements in the p sublevel block, the highest energy valence electrons are found in p orbitals.
What is a sublevel in electron configuration?
The sublevels contain orbitals. Orbitals are spaces that have a high probability of containing an electron. In other words, an orbital is an area where the electrons live. There can be two electrons in one orbital maximum.
How do I find my sublevel name?
An electron configuration shows the electrons distribution by sublevel using the quantum numbers n and l, where the notation for l is by its letter designation (s, p, d, f, etc.). For example, the notation 3d4 indicates 4 electrons in the d sublevel (l=2) of the n =3 principal energy level.
What is the difference between sublevel and orbitals?
One can think of an orbital as being the space where electrons inhabit. An orbital can contain a maximum of two electrons. Thus the “s” sublevel, which has only one orbital, can have only two electrons. Similar patterns are followed in other sublevels as well.

What is the shape of a sublevel?
Sublevels. Each of the four sublevels have a specific shape or area where electrons can be found. As shown in Figure 3.6, the s sublevel has a spherical shape, the p sublevel has a dumbbell shape, and the d sublevel has a four leaf clover shape.
How many electrons does each sublevel hold?
The subshells s, p, d, and f contain the following number of orbitals respectively, where every orbital can hold up to two electrons maximum: s: 1 orbital, 2 electrons. p: 3 orbitals, 6 electrons. d: 5 orbitals, 10 electrons.
What are sublevels and Subshells?
Sublevel or subshell Each energy level, or shell, is divided into sublevels. The terms sublevel and subshell are used interchangeably. The sublevels are represented by the letters s, p, d, and f. Each energy level has certain sublevels. The chart below shows the sublevels that make up the first four energy levels.
What is 1s 2s 2p 3s 3p?
1s 2s 2p 3s 3p represents the electron orbital energy levels.
