What are the blocks of the periodic table? Depending on the number of electrons in the electron shell (electron configuration), the elements of the periodic table are divided into blocks. At present there are four different blocks with the s, p, d and f blocks. The g-block, which concerns the superactinoids, is currently still hypothetical, since no corresponding element has yet been detected.
Atomic mass, symbol and atomic number Cobalt is a naturally occurring element with the elementary symbol Co and atomic number 27. In the periodic table it stands with an atomic mass of 58,933 u in the eighth subgroup. The chemical element discovered by Georg Brandt in 1735 is not radioactive and is in a solid state of aggregation at room temperature.
Structure and function of the leaf Cuticle / Cuticle (lat. Cutis = skin) covers the outer walls of the epidermis; consists of a water-impermeable, hydrophobic wax layer, which prevents the evaporation of water. Epidermis (Greek epi = over, derma: skin) is located between cuticle and palisade tissue; transparent, there are no chloroplasts in the epidermis, so that light comes through to the palisade tissues; the cell walls of the epidermis give the leaf stability and protect against external influences palisade tissue: located between epidermis and sponge tissue; very rich in chloroplasts responsible for photosynthesis Sponge tissue: between palisade tissue and cuticle; only a few chloroplasts compared to the palisade tissue; Main function: Control of gas exchange -> CO 2 diffuses into the leaf, O 2 and H 2 O out Steam guard cells / stomata: are located on the leaf underside in the epidermis.

Definition: The brain (Greek enkephalos) is probably the most complex organ of the human body. In the head is the approximately 1.3 kg, walnut-shaped brain, surrounded by the stable skull bones, which should protect it from external influences. As part of the central nervous system, the brain is the central hub for all processes in the body.
Atomic mass, symbol and atomic number Chromium is a naturally occurring element with the elementary symbol Cr and the ordinal number 24. In the periodic table it stands with an atomic mass of 51.996 u in the 6th subgroup. The chemical element discovered by Louis Vauquelin in 1797 is not radioactive and is in a solid state at room temperature.
Structure and function of the human ear The sense organ ear is responsible in humans for the perception of sound. Sound waves are transmitted to the cochlea through the ear canal, via the eardrum and the calyx, where they are converted by the sensory cells into electrical impulses (transduction).
