Indicate which subatomic particle (proton, neutron, or electron) correctly matches each of the following phrases. More than one particle can be used as an answer.
- a. possesses a negative charge
- b. Has no charge
- c. has a mass slightly less than that of a neutron
- d. Has a charge equal to, but opposite in sign from, that of an electron
(a)
Interpretation:
The subatomic particle that possesses a negative charge has to be given.
Concept Introduction:
Atoms are made up of even smaller particles. These particles are very small and these are all the building blocks of atoms and they are known as subatomic particles. Protons, electrons, and neutrons are the subatomic particles that are found in atom. Electrons possess a negative electrical charge. Protons possess a positive electrical charge. Neutrons possess no charge and they are neutral.
If the mass is considered to one unit based on one electron, then the relative mass of a proton is equal to 1837 electrons and neutron is equal to 1839 electrons. Neutron is slightly higher in mass than that of a proton.
Explanation of Solution
An atom is made up of subatomic particles namely, electron, proton, and neutron. The subatomic particle that possesses a negative charge is electron only. This is present outside the nucleus of an atom.
(b)
Interpretation:
The subatomic particle that possesses no charge has to be given.

Explanation of Solution
An atom is made up of subatomic particles namely, electron, proton, and neutron. The mass of an atom is mainly contributed by the proton and neutrons that are present in the nucleus. Neutrons do not possess any charge and it has mass slightly higher than that of proton.
(d)
Interpretation:
The subatomic particle that has equal opposite charge from that of an electron has to be given.

- Choose an element from the periodic table that is found in the human body, and write five sentences about some of its functions in the body.arrow_forwardAtoms A and B interact to form a compound, AB2. When measured, atom A has a partial negative charge and atom B has a partial positive charge. From this information, we can conclude what? Select only ONE answer choice. Note: - means "approximately equal to" , A > B means "A is greater than B" , and A B: AB2 is hydrophilic Not enough information to answer the questionarrow_forwardIf you have a sample of unknown composition, a first step at analysis might be a determination of the masses of the atoms and molecules in the sample. A mass spectrometer to make such an analysis can take various forms, but for many years the best technique was to determine the masses of ionized atoms and molecules in a sample by observing their circular paths in a uniform magnetic field, as illustrated is shown. A sample to be analyzed is vaporized, then singly ionized. The ions are accelerated through an electric field, and ions of a known speed selected. These ions travel into a region of uniform magnetic field, where they follow circular paths. An exit slit allows ions that have followed a particular path to be counted by a detector, producing a record of the masses of the particles in the sample. The moving ions can be thought of as a current loop, and it will produce its own magnetic field. The direction of this field at the center of the particles’ circular orbit isA. In the…arrow_forward

Plasma, the "fourth state," is characterized by lack of shape, and it cannot be classified as gas, liquid, or solid. Examples of plasma are plasma ball and the contents of a fluorescent bulb. The fifth state has already been discovered by scientists. It is called Bose-Einstein Condensate (BEC), but in Grade 3, the focus of study is only on the three states of matter: solids, liquids, and gases. Let us have some exercises on grouping of matter.
