Questions and Answers
- 1.
Smallest piece of matter that if you divided it, it would no longer be matter.
Explanation
An atom is the smallest unit of matter that retains the properties of an element. If you were to divide an atom further, it would no longer have the characteristics of matter. Atoms consist of a nucleus, which contains protons and neutrons, surrounded by electrons. They are the building blocks of all matter and cannot be broken down into smaller particles without losing their identity as matter. Therefore, an atom is the correct answer to the question.Rate this question:

Number of protons plus the number of neutrons in the nucleus of an atom.
Explanation
Atomic mass is the sum of the number of protons and neutrons in the nucleus of an atom. It represents the total mass of an atom and is usually expressed in atomic mass units (amu). The protons and neutrons contribute to the mass of an atom, while the electrons, which have much smaller mass, are not included in the atomic mass calculation. Therefore, the atomic mass is a measure of the total number of particles in the nucleus of an atom.Rate this question:

Uncharged particle in the nucleus of an atom
Explanation
A neutron is an uncharged particle that is found in the nucleus of an atom. It is one of the three fundamental particles that make up an atom, along with protons and electrons. Unlike protons, which have a positive charge, and electrons, which have a negative charge, neutrons have no charge at all. They play a crucial role in determining the stability and properties of an atom, as they help to balance out the positive charge of the protons in the nucleus.Rate this question:

Positively charged particle that is in the nucleus of every atom
Explanation
A proton is a positively charged particle that is found in the nucleus of every atom. It is one of the fundamental particles that make up an atom. The nucleus of an atom consists of protons and neutrons, with protons carrying a positive charge and neutrons carrying no charge. The number of protons in an atom determines its atomic number and defines the element. Therefore, the statement "Positively charged particle that is in the nucleus of every atom" accurately describes a proton.Rate this question:

Number of protons in the nucleus of an atom of an element
Explanation
The atomic number of an element refers to the number of protons in the nucleus of an atom of that element. Protons are positively charged particles and their number determines the element's identity. Each element has a unique atomic number, and it is used to organize elements in the periodic table. Therefore, the correct answer is "atomic number".Rate this question:

Region surrounding the nucleus of an atom
Explanation
The region surrounding the nucleus of an atom is known as the electron cloud. This cloud is made up of electrons that are constantly moving in specific energy levels or orbitals. The electrons in the cloud are not fixed in specific positions, but rather exist as a probability distribution. This means that the exact location of an electron within the cloud cannot be determined precisely, but rather the cloud represents the area where an electron is most likely to be found. The electron cloud plays a crucial role in determining the chemical and physical properties of an atom.Rate this question:

Negatively charged particle that is part of every kind of matter.
Explanation
An electron is a negatively charged particle that is found in every kind of matter. It is a fundamental particle and is one of the building blocks of atoms. Electrons orbit around the nucleus of an atom and are responsible for the electrical properties of matter. They play a crucial role in chemical reactions and the flow of electricity. Electrons have a very small mass compared to other particles and can be easily influenced by electric and magnetic fields.Rate this question:
- 8.
Matter that is made up of only one kind of atom
Explanation
An element is a substance that consists of only one kind of atom. This means that all the atoms in an element have the same number of protons in their nucleus. Elements cannot be broken down into simpler substances through chemical reactions. They are the building blocks of all matter and are represented by symbols on the periodic table.Rate this question:
