Scientists were able to confirme that organism would be made of cells because they could see the cells in the tissue placed under the microscope so without the microscope they would of never known if the theory was true
Well it’s simple science not rocket science when an object falls. It’s gravitational potential turns into kinetic.
Answer:
There are three factors that help in the prediction of the trends in the periodic table: number of protons in the nucleus, number of energy levels, and the shielding effect. The atomic radii increase from top to the bottom in any group. The atomic radii decrease from left to right across a period.
Explanation:
Major periodic trends include atomic radius, ionization energy, electron affinity, electronegativity, valency and metallic character. These trends exist because of the similar electronic configuration of the elements within their respective groups or periods and because of the periodic nature of the elements.
Answer:
6
Explanation:
If there are 6 electrons and it has a balanced charge, there also must be six protons.
Answer is: chemical.
If the arrangement of particles is changed, that is chemical change or chemical reaction (new substance is formed).
In physical change, the bonds between oxygen and hydrogen can not be separated.
For example, balanced chemical reaction: 2Mg(s) + O₂(g) → 2MgO(s).
Chemical changes (chemical synthesis) is when a substance combines with another (in this example magnesium and oxygen) to form a new substance.
