Elements On The Periodic Table 3/26/17

Summary:
The number of protons determines the identity of the atom. In order to make an ion we lose or gain electrons. When atoms gain electrons they become negative ions. These are called anions. When atoms lose electrons they become positive ions. These are cations. Isotopes are atoms of the same element with different number of neutrons. The number of neutrons determines whether the atom is stable or not. All atoms of a particular element have the same atomic number. Isotopes of the same element have different mass number. A smoke detector measures isotopes in the air to determine if there is a fire. The atomic number is how many protons there are in the atom. There are no decimals because you cannot have a part of a proton. The element symbol is normally an abbreviation of the element name. The mass number is the neutrons and protons added together.
S&EP-Using Mathematics: We completed this worksheet in which we were given some number or part of the element. Those include the charge, atomic number, atomic mass, name or symbol. For each element we were given a couple of pieces of information and required to fill out the rest. For example, we knew the element was gold, it had a positive charge of three, it had 79 protons and the atomic mass was 195. From that i took the 79 as the atomic number. After that, I subtracted 79 from 195 to get 116 or the number of neutrons. From there I had to figure out the number of electrons. I knew that there were 79 protons and there was a positive charge of three. That meant that there were three less electrons that protons. I subtracted three from 79 to get 76 which was the number of protons. We had to do this quite a number of times with different elements, numbers and pieces of information. This showed me how math and science are connected and sharpened my math skills a bit.
XCC-Structure & Function: Mendeleev organized the elements based on their atomic mass and properties. He organized them in such a periodic way it became known as the Periodic Table of Elements. As you go down the families or columns you can see how each have a new energy level, but as you move to the right or through the periods they gain electrons and proton. In other words and you move down the row, the atomic number increases by one. As well as that, the families always have the same amount of electrons in its most outer layer. Everything on the left side of the periodic table is metals. The first family is alkali metals. They are highly reactive with halogens or family seven. Can you guess why? Well, it's because alkali metals have one electron in its most outer layer while halogens have seven. Having a full set means having eight and one plus seven equals eight. That means that noble gasses or family eight are stable or not reactive because they have a full outer energy level.
Multiplier: This week I was a mutant, to be more specific a learner because this was a new topic that I really wanted to understand.
