Answer:
The center of an Atom is called the Nucleus.
Explanation:
Answer: the center of an atom is called the nucleus and is made of protons and neutrons
Explanation:
Yes, Sharpies contain volatile solvents—and when inhaled these solvents can produce a "high." The effects of inhalants (including Sharpies) can be similar to those of alcohol and include slurred speech, lack of coordination, euphoria, and dizziness.

A metallic bond is held together by electrostatic forces of interaction, while an ionic bond is held together by electrostatic forces of attraction by oppositely charged cations and anions. The ionic bond has one atom donate electrons to become positively charge while the other atom receives electrons and becomes negatively charged. The opposite charges then attract one another to create the electrostatic force of attraction. In contrast, the electrons in a metallic bond are delocalised, then the nucleus attracts this free moving electrons to establish electrostatic forces of interaction. The structure shows positive charge surrounded by negative charge.
The easiest way to go about this would be to check out their physical properties. Physical properties are those attributes of a substance or material that can be observed or measured without altering or changing the composition of that material.
So we can check out the following physical properties:
1. Color. Check if there is any difference in color.
2. Weight. If possible, take similar sized pieces of the two and note any difference in weight .
3. Texture. Are they smooth or rough to the touch?
4. Smell or odor. Check out any unique smell.
5. Solubility. Dissolve a bit of each in water and see how soluble each is.
6. Melting point. Carefully heat a piece of it and see if they will melt, and if so at what temperature.
7. Pliability. Can any of them bend, are they flexible?
8. Magnetism. Can the be attracted by a magnet?
9. Bouyancy . Can they float on water?
10. Electrical conductivity. using a battery and small torch bulb, find out if they can conduct an electric current.
These 10 physical tests can help differentiate between the two materials. There are still many more that can be safely carried out.
To determine whether two solid substances are the same, measure their mass and volume, and perform additional tests if needed.
When trying to determine whether two solid substances are the same, there are several measurements and tests you can perform. Firstly, you can measure the mass of both substances using a balance. Secondly, you can measure the volume of both substances using a graduated cylinder or other measuring tools.
In addition to this, If the mass and volume are the same for both substances, it is likely they are the same. However, to confirm this, you can perform additional tests such as melting point determination or spectroscopy to analyze the chemical properties of the substances.
