Ionic bonding 10/29

Summary: This week in class we learned about ionic bonding. Ionic bonding happens when two atoms (metal and non-metal) share an electrons. The atom with the most valence electrons which are the electrons on the outer most shell of the atom, receives an electron from the atom with lesser amount of valence electrons. Then the atoms attract because the atom that got the electron is now a negative ion and the atom that gave the electron is now a positive ion, and then the atoms  bond together to make an ionic bond.

SP2: Developing and using models
This week in class we used model atoms with clay on them to represent electrons. We then were given a sheet of paper with 5 bonds we had to do. We then had to determine whether the bond was ionic or covalent. If the bond was ionic we would give the atom that had more valence electrons an electron from the other atom. If it was a covalent bond then we put the atoms on top of each other.

Covalent bonding 10/20

Summary: This week in class we learned about covalent bonding. A covalent bond is formed when two atoms want to take each others electrons. When an the atoms want to take an electron they get closer to the electron. When they get closer to the electron then it begins a loop where the atoms try to get closer to each others electrons bet cannot. YOu cannot have H3O because the amount of inner electrons cannot go over two and the outer electrons do no have strong enough bond to the nucleus for covalent bonds to form.

SP4: Analyzing and interpreting data
This week in class we analyzed data by getting a document with links on it and then reading what each website had to say very carefully. We also analyzed an image that showed us how electrons work in covalent bonding. We interpreted the data in a document that we were given we answered the questions on the document based off of our research

Periodic Table 10/1

Summary: This week in class we learned about the Periodic Table of Elements. The Periodic Table is how we organize the atom elements based on the increasing atomic number aka the number of protons. The other way the table is sorted is atomic families that take on similar atomic properties like reactivity of the atom. Other information the Periodic Table of Elements gives is the atomic mass (protons + neutrons) and the atomic charge (Protons - electrons depending which has more).

SP5: Using mathematics and computational thinking
This week in class we used mathematics to calculate various things for the periodic table. The first thing we used math calculate was the charge of an element by finding what amount of protons or electrons were higher then subtracting them to find the positive (more protons) or negative (more electrons). We then used math to calculate the atomic mass of an atom by adding the protons and the neutrons
