Week 4 Chemical elements

- written by user Katsampoxaki-Hodgetts Kallia

Today we will be discussing properties and trends of P block and in particular the nitrogen family (Group 15).

Note-taking task https://www.youtube.com/watch?v=oLrcnmgFm_0

As well as working on note-taking and vocaulary skills, we will learn how to design powerpoint slides and based on the reading we will create word-tables in preparation of our own presentation.

We will also talk about cohesion and coherence using an excerpt from our EAP Chemistry book pg 49-51 on Fluorine.

Student handout for this week is in Files (Εγγραφα).

P block elements are good conductors of heat and electricity, since they lose electrons easily. They have high melting points and react with nonmetals to form ionic compounds. Maria Kakodeipnaki (3094), Danielita Danai(3181), Melina Alinejad (3096)

P block elements: shiny,good conductors of heat and electricity,lose electrons easily,high melting points Nitrogen family elements: their compounds may be diamagnetic or paramagnetic and may conduct electricity when heated Fani Troullinou 3093 Celia Poulia 3169 Manos Oikonomakis 3146

p-block elements are those in which the last electron occupies p-orbitals and are found in groups 13, 14, 15, 16, and 17 (except helium). Because p-block orbitals can only hold a maximum of six electrons, p-block elements are classified into six groups. Some metals, all nonmetals, and metalloids are among these elements.

The elements that belong in the 14-17 groups of the periodic table The number of electrons in the p-block elements is either 2 or 8 or 18 There is a consistent increase in non-metallic character from left to right and the metallic from right to left They include carbon,nitrogen,oxygen and flourine in addition to noble gases One of the most important compounds of p-block elements are ammonia and ozone and sulphuric acid which is considered the “King of chemicals” Angeliki zervou , Stella Tsiourva, Nikolas Spontidakis.

•Eugenia Roussou, Katerina-Aliki Keller, Metaxia Papadaki, Ioanna-Aspasia Tsiliou •P block elements: Elements of P Block1) have 3 atomic orbitals 2) provide space for 6 electrons 3) They are shiny 4) are included in 6 main groups 5) Include the noble gases, both metals and non- metals 6) They tend to let go of electrons.

Konstantina Harou Katerina Androulaki Irene Gonianaki Properties of elements of p block: Their last electron enters any of the three p-oebitals of respective shells. They have high electronegativity. They are good conductors of heat and electricity. There is a consistent increase in non-metallic character from left to right and decreases from top to bottom in the groups. In the p block of periodic table, halogens are included.

Properties of P Block Elements The P-block elements consist of a wide group of elements. They span over a very large portion of the table, which helps to explain why the properties of the p-block elements change rather drastically from the far left side of the block to the far right side. The farther apart elements are on the table, the more likely they are to have differences in their properties (Ντενιερο Ταραι 3162, Εμμανουέλα Βελουση 3177)

P block elements are classified into six groups:13,14,15,16,17 and 18( except from helium). The number of electrons in the p-block elements’ penultimate shell is either 2,8 or 18. Also p block elements are highly electronegative, such us F, Cl , O and others. There is a consistent increase in non-metallic character from left to right and from bottom to top.

The p-block elements are in the right side of the periodic table. They have negative charge, they lose their electrons easily and they are capable to make strong bonds with the metals. Ourania Kastritsi Eirini Manousaki

Ioakeimidou Palieraki the elements that belong to the groups 13th - 18th of the periodic table. P block elements have classic metal characteristics and they have their valence electrons in a p orbital. Some of the p block elements are the oxygen, the nitrogen, the flurine

Zoi Linaraki, Vasilis Kopidakis: they are shiny they are good conductors of heat and electricity and they lose electrons easily. These metals have high melting points and readily react with nonmetals to form ionic compounds

P block elements belong from the 13th to the 18th group of periodic table. In the p block belong the non metals and the metalloids. Additionally they have small atomic range. Most of them are gases. Also in the p block belong the noble (kind) gases. Their last electron is in the p sub-shell. Last but not least they can only receive 8 electrons in the outer shell. With greetings, Paulos Kriaras, Stavros Alatsakis, Anastasis Varaklas.

There are 6 groups of people block elements on the periodic table. They are numbering from 13 to 18. Their valence electrons are in a p orbital. The nitrogen family belongs to the p block of periodic table. The elements located in the p block of the periodic table are electronegative. Maria Charoniti 3132 Eleni Samaritaki meteg

Ελένη Χατζακη Παναγιωτα Τόγια It has at least 6 electrons so this block includes six main groups of elements . The halogens and the noble gases belong to this block . They are right at the periodic table so they have small atomic radius.
