Answer:

Any element can always be identified by its number of protons and atomic number.

Explanation:

All atoms are composed of a central nucleus in which there are particles with a positive electric charge, the protons, around which other particles with a negative electric charge that are electrons move. Thus, the atom is electrically neutral, since the positive charge of the protons is compensated by the negative charge of the electrons.

Atoms of different elements have different amounts of protons. The atomic number (which is identified by the letter Z) indicates the amount of protons that is present in the nucleus of an atom. This number is then responsible for defining the electronic configuration of the atom and the chemical properties of the element. Then it is possible to say that the number of protons in the nucleus, that is to say the atomic number Z, of an atom determines its identity. For this reason, the atomic number allows the ordering of the various chemical elements in the periodic table.

Finally, <u><em>any element can always be identified by its number of protons and atomic number.</em></u>

The answer is c. number of protons and d. atomic number. The proton number can identify an element. And also the atomic number is equal to the number of protons.

yuradex [85]

Answer:

heat; temperature; surrounding; insulated.

Explanation:

A calorimeter can be defined as a scientific instrument (device) that is designed and developed for measurement of the heat involved in chemical reactions or other processes, especially by taking the measurement of the temperature of the materials surrounding the process.

Basically, a calorimeter is insulated using materials with a very high level of resistivity, so as to prevent heat transfer to the outside of the device (calorimeter).

Some of the components that make up a simple calorimeter are; thermometer, an interior styrofoam cup, an exterior styrofoam cup, cover, etc.

Additionally, a calorie refers to the amount of heat required to raise the temperature of a gram of water by one degree Celsius (°C)

If electrons were used in the two-slit experiment instead of light, what change would need to be made to the slit spacing in ord
Andrei [34K]
In order to conduct the two-slit experiment with a beam of electrons, the slit opening has to be smaller than the opening for the light waves. This is because the wavelength of the electron beam is lower, which means it will pass through the large slit without diffracting. Diffraction will occur if the spacing is reduced. The reason that electrons have a smaller wavelength is because they have a higher energy than light waves.
