The main features of representative gases

Top Representative Elements Here in this page we are going to discuss about concept called representative elements.

The main features of representative gases

What are some examples of arthropods? Ants, flies, cockroaches, shrimp, crabs, spiders and scorpions are examples of arthropods. Phylum Arthropoda - Image Diversity: What are the classes into which the phylum Arthropoda is divided?

What are the three main classes and some of their representative species? The three main classes of arthropods are: Other classes are onychophorans velvet wormsdiplopods millipedes and chilopods centipedes.

Arthropods present three distinguishing features: In terms of germ layers and the presence of a coelom, how can arthropods be described? Arthropods are triploblastic they have three germ layers and are coelomate organisms.

Considering the presence of segmentation metameres in their body, which previously studied phylum resembles arthropods? Given their metameric structure, arthropods are evolutionarily closer to annelids, as they also have segmented bodies.

In the embryonic development of some arthropods the fusion of metameres takes place, forming structures such as the cephalothorax of arachnids, for example. What is the external rigid shell of arthropods called?

What is it made of? Which type of organic molecule is that substance? The external shell of arthropods is called the exoskeleton. The exoskeleton of an arthropod is made of chitin, a nitrogen-containing polysaccharide.

Phylum Arthropoda

How do arthropods grow? Due to the presence of the exoskeleton, the growth of arthropods is periodical. During the growth period, the animal loses the exoskeleton, grows and develops a new exoskeleton.

This process is called ecdysis or molting. How does the presence of the exoskeleton explain the small size of arthropods in general?

How can the features of the exoskeleton in arthropods explain the environmental adaptation of some species of the phylum? This feature was fundamental in allowing primitive arthropods from the sea to survive on dry land without losing excessive water to the environment. What type of digestive system is present in species of the phylum Arthropoda?

Are these animals protostomes or deuterostomes? The digestive tract of arthropods is complete, containing a mouth and an anus.Many of the representative elements on the right side of the periodic table are nonmetals. The nonmetals in group 18 are called the noble gases, and they mostly do not form bonds with other elements because their electron configurations are stable on their own, although there are exceptions.

The representative elements are those found in the first two groups of the periodic table and in groups 13 through They are also referred to as the main-group elements and comprise all known elements, except the transition metals located in .

Gases, Liquids, and Solids

The periodic table organizes elements into groups based on similar properties. There are three main states of matter: solids, liquids and gases.

The main features of representative gases

Liquids are considered the second state, between solids and gases. Liquids are similar to solids in that their particles are packed tight enough that they cannot be compressed further.

The main features of representative gases

In contrast, gases have particles that have large amounts of . Yes noble gases are representative elements as they are members of p block.

The representative elements are s and p block elements This page may be out of date. The noble gases are group 18 on the periodic table, which is the column of elements on the right side of the table.

There are seven noble gas elements: helium, neon, .
