1-18-12 how many protons, neutrons, and electrons could it have?

Lanthanum,20 protons 24 neutrons 20 electrons

1-17-12 How many neutrons does it have and what is the name of the element?

The element has 16 neutrons and the element name is phosphorus.

1/11/12 The 3 subatomic particles are protoms, neutrons, and electrons. List, in ascending order, the subatomic particles sizes and their changes.

The ascending order is electrons with a no charge, neutrons with a negative charge, and last protons with a positive charge.

1-10-12 What does the period (row) on the periodic table tell you about elements in that row?

The period (row) on the periodic table tell you about elements in the row and the atomic number. That is why there are numbers at the top of every row. But in some cases the elements in that row may not tell you the right atomic number.

1/9/12 What is matter?

1-6-12 Compare and contrast molecules and compounds.

A molecule is two of the same things chemically combined.It's like taking two pieces of gum and putting them together, the can be the same color or different.
A compound is two different pieces of gum chemically joined together, like a green piece of gum and a red piece of gum.
A compound is two or more atoms.
A molecule is two of the same atoms.

1-5-12 five parts of an atom

Nucleus
Neutron
Proton
Electron
Electron Cloud

1-5-12 In an atom what does each of your five parts do?

- The electrons control the atom because the electrons are on the outer side of the nucleus acting like a shield.
- When you change the number of neutrons in the nucleus you will end up with a different name. so then the neutrons control what kind of element.
- The protons control the weight of the atom.
- When the numbers of protons and electrons aren’t equal you will end up with an unequal. so then the protons and electrons control the balancy in the element.
- The electron cloud is the cloud the holds the electrons.
- The nucleus is the very middle or the center of the atom.

1-4-12 What is the break down of an atom?

The breaK down of an atom is first the nucleus, which is in the middle or the center of the atom, then on the outer side of the nucleus is the elctron cloud.

1-3-2012 What are your career aspiration?

When I graduate from college my career aspiration is to become a Marine Biologist. The reason why I would like to be a Marine Biologist is because I like sea animals and I want to be some kind of scientist and it pays good money.
