1) The nucleus of an atom loses 2 protons and 4 neutrons.
2) The nucleus of an atom gains a proton and it's neutrons remain the same.
<span>The scientific method is a systematic way of questioning about the world around us and answering questions. The number of steps varies from one description to another, mainly when data and analysis are separated into separate step, but this is a fairly standard list of 6 scientific method steps, which you are expected to know for any science class:
1. Form a Hypothesis. This is a sort of educated guess about what you expect.
2. Design an Experiment to test your hypothesis. An experiment has an independent and dependent variable. You change or control the independent variable and record the effect it has on the dependent variable.
3. Conduct Experiment
4. Record data and observations and analyze what the data means. Often, you'll prepare a table or graph of the data.
5. Form a Conclusion. Conclude whether to accept or reject your hypothesis. Communicate your results.</span>
Answer:
The particles in a solid are tightly packed and locked in place. ... The particles in a liquid are close together (touching) but they are able to move/slide/flow past each other. The particles in a gas are fast moving and are able to spread apart from each other.
Explanation:
Let us calculate the structure of the electric shells of the Al atom. It has an atomic number of 13, so it has 13 electrons. The first 2 go to the first hell. The next 8 need to go to the second shell and the last 3 ones would go to the outermost shell. The outer shell, that is the most important one for chemical reactions, has thus 3 electrons. An atom always tries to have a completed outer shell (with either 2 or 8 atoms). It is easier for a cell to have a charge of +3 than a charge of -5 (smaller absolute value) and thus the Aluminum atom will try to get rid of the 3 electrons. In this process, it loses negative charge thus it will become positively charged. Hence, the correct answer is that it will prefer to lose 3 electrons and become positively charged.
All oxayacids have cations so no need to name the cation (H+) If name of polyatomic anion ends in -ate change to -ic for acid and if it ends with -ite change to -ous for acid
example:
ion nitrate is called nitric acid
ion nitrate is called nitrous acid
