General Periodic Table:
1. State the periodic law in your own words.
Chemical and physical properties of elements repeat in each period when elements are arranged in order of atomic mass

2. How do the properties analyzed in this activity show periodicity of the chemical elements? That is, as the atomic number increases, when do the trends repeat?
For the most part, the trend carried out throughout the period. However there were some cases when Argon, a noble gas did not follow a trend and another case where the trend was interrupted due to the …show more content…

What is electronegativity?
Electronegativity measures the ability of an atom to attract a bonding pair of electrons.

16. What is the most electronegative element and where is it found on the periodic table? (Top, bottom, left, right?)
Fluorine is the most electronegative element; it is a halogen and is found in the upper right corner of the periodic table.

17. Where are the least electronegative elements found? (Top, bottom, left, right?)
The least electronegative elements are found towards the bottom left of the periodic table (the opposite corner of fluorine)

18. What appears to be the trend in electronegativity as you move from left to right in a row?
Electronegativity increases as we move from left to right

19. What appears to be the trend in electronegativity as you move from top to bottom in a column?
Electronegativity decreases as we move from up to down

20. List the following atoms in order of increasing electronegativity: O, Al, Ca
Ca, Al, O

21. List the following atoms in order of decreasing electronegativity: Cl, K, Cu
Cl, Cu, K

4.) I noticed that there is a relationship between the ionic radius and the atomic number of the representative elements in Group 1A. The higher the atomic number, the bigger the ionic radius is. So, while hydrogen has an atomic number of 1 and Francium has an atomic number of 87, it is safe to assume that FR has a higher ionic radius. This is true; the ionic radius for Hydrogen is 0.012, and for Francium, it is 0.194.

Task 1 (P1) The periodic table is laid out into groups and periods. They are also put into different blocks S-Block, D-Block, P-block and F-Block due to their energy levels. They are organised by their energy levels and chemicals properties. As the elements go along the periods in the periodic table the electronegativity increases but as the elements go down the groups the electronegativity decreases.

Where as, electrons are negatively charged(Doc.3).The neutron is the dense middle of the atom(Doc.3). The protons and neutrons in the atom are in the nucleus(Doc.3). However, the electrons preside in electron clouds outside the nucleus(Doc.3). To sum up, an atom is a small structure that defines what an element is and

Ionization energy increases as you go from left to right of an element’s period. This is mainly due to the fact that the atomic radius generally decreases when you move across the element’s period, therefore there is a greater effective attraction between the negatively charged electrons and positively-charged nucleus. The ionization energy of a nitrogen is calculated as 1400

Although not linear, a trend that is established is that as one looks across a period there is an increase in density until around group 11 in period IV. This trend varies depending on the row being examined but for the most part has an increase, an area of consistency, then a decrease. This trend can be observed based on the graph comparing Period IV density and atomic number. The point of decrease occurs around atomic number 28.

For instance, when N2 is formed, three pairs of electrons are shared, leading to the two particles having 8 valence electrons. When KBr is formed, the two elements also have 8 valence electrons. Furthermore, electrons in ionic bonds and covalent bonds are fixed, however, in metallic bonds, they are delocalized, which means electrons are able to flow freely. In the lattice of NaCl, electrons are restricted in specific space and it’s the same with oxygen compared with electrons in iron which are

As atoms go down a family, they become more metallic. Since they are becoming more metallic, the atoms want to lose electrons and therefore don’t hold the electrons as tightly, also making the atom larger. Typically as elements go across a series, they decrease in

This group consist of Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium. These metals are very soft and can usually be cut with a knife. They have a very low melting and boiling point. Densities of these elements are very small, and the electronegativity is low. Alkali metals are the most reactive metals.

Protons are positively charged, neutrons are not charged and electrons are negatively charged. The proton and the neutron are stuck together, that is called nuclei, and the electron orbits the nucleus in a wave like motion. The amount of protons, neutrons, and electrons can change, creating different atoms with different energy levels.
