Correct Answer
C. Are positively chargedExplanation
Protons are positively charged particles found in the nucleus of an atom. They have a charge of +1 and a mass of approximately 1 atomic mass unit (amu). Unlike electrons, which are negatively charged and orbit the nucleus, protons are tightly bound within the nucleus. Their positive charge balances the negative charge of electrons, creating a neutral atom.Rate this question:

Correct Answer
A. Orbit the nucleus and negatively chargedExplanation
Electrons orbit the nucleus and are negatively charged. This is a fundamental concept in atomic structure. Electrons are subatomic particles that revolve around the nucleus in specific energy levels or orbitals. They carry a negative charge, which is equal in magnitude to the positive charge of the protons in the nucleus. The arrangement of electrons in these orbitals determines the chemical properties and reactivity of an atom.Rate this question:

Correct Answer
D. Is the same as the amount of protonsExplanation
The atomic number of an atom refers to the number of protons in its nucleus. Protons are positively charged particles, and the atomic number determines the element and its properties. It also determines the number of electrons in a neutral atom, as atoms are electrically neutral and have the same number of protons and electrons. The atomic number is a fundamental characteristic of an element and is used to organize the periodic table.Rate this question:

An atom is the smallest particle you can get. There is nothing smaller than an atom.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because an atom is indeed the smallest particle that exists. Atoms are made up of protons, neutrons, and electrons, and they cannot be divided further without losing their chemical properties. Subatomic particles such as quarks and leptons exist within atoms, but they are not considered as separate particles on their own. Therefore, an atom is the fundamental building block of matter and cannot be broken down into anything smaller.Rate this question:
