What does the symbol in the upper left-hand corner stand for?
A.
Atomic Number
B.
Mass of the Element
C.
How many electrons
Correct Answer A. Atomic Number
Explanation The symbol in the upper left-hand corner represents the atomic number of an element. The atomic number is a unique identifier for each element and it represents the number of protons in the nucleus of an atom. It is an important characteristic of an element as it determines its position in the periodic table and its chemical properties.

3.
Which is equivilant to the atomic number?
A.
Protons
B.
Orbits
C.
Electrons
Correct Answer A. Protons
Explanation The atomic number of an element is equal to the number of protons in its nucleus. Protons are positively charged particles found in the nucleus of an atom. The number of protons determines the identity of the element, as each element has a unique number of protons. Therefore, the correct answer is protons. Orbits and electrons are not equivalent to the atomic number, as orbits refer to the path followed by electrons around the nucleus, and electrons are negatively charged particles found in the electron cloud surrounding the nucleus.

What are the large letters on the elements?
A.
Large letters
B.
Chemical symbol
C.
Atomic number
Correct Answer B. Chemical symbol
Explanation The large letters on the elements refer to the chemical symbol. Each element in the periodic table is represented by a unique chemical symbol, which is usually a one- or two-letter abbreviation of its name. These symbols are used to identify and differentiate between different elements. The chemical symbol provides a concise and standardized way to refer to elements in various scientific and educational contexts. It is an essential component of the periodic table and is widely recognized and used by chemists and scientists worldwide.

5.
Where is the most of the mass located in an atom?
A.
The protons
B.
The protons and electrons
C.
The electrons
D.
The electrons and neutrons
E.
The neutrons and protons
Correct Answer E. The neutrons and protons
Explanation The correct answer is the neutrons and protons. Neutrons and protons are located in the nucleus of an atom, which contains most of the mass. Electrons, on the other hand, are much smaller in mass and are found in the electron cloud surrounding the nucleus.

6.
Each atom has a nucleus which contains _______ which are positively charged.
Correct Answer protons
Explanation Atoms have a nucleus at their center, and the nucleus contains positively charged particles called protons. These protons are essential for determining the atomic number and overall charge of the atom. They are tightly packed within the nucleus and contribute to the overall stability and structure of the atom.

7.
A(n) ____ is the smallest part of an element that has all of the properties of that element.
Correct Answer atom
Explanation An atom is the smallest part of an element that has all of the properties of that element. Atoms are composed of subatomic particles such as protons, neutrons, and electrons. These particles determine the chemical and physical properties of an element. Atoms combine to form molecules, which are the building blocks of matter. Therefore, an atom is the fundamental unit of an element, representing its unique characteristics and behavior.

8.
Orbiting the nucleus of an atom are negatively charged particles called ____.
Correct Answer electrons
Explanation Electrons are negatively charged particles that orbit the nucleus of an atom. They play a crucial role in determining the chemical and physical properties of an element. Electrons are responsible for forming chemical bonds, participating in chemical reactions, and determining the overall behavior of atoms. Without electrons, atoms would not be stable and would not be able to form compounds. Therefore, the correct answer is electrons.

9.
Each atom has a nucleus which contains _______ which are not charged.
Correct Answer neutrons
Explanation Atoms have a nucleus at their center, which contains neutrons. Neutrons are subatomic particles that have no charge. They are located alongside protons, which have a positive charge, within the nucleus. The neutrons help to stabilize the nucleus and contribute to the mass of the atom.
Rate this question:
10.
The number of protons plus the number of neutrons determines an atoms ___.
Correct Answer atomic mass
Explanation The atomic mass of an atom is determined by the sum of its protons and neutrons. Protons have a positive charge and are located in the nucleus of an atom, while neutrons have no charge and are also found in the nucleus. Since the atomic mass is the total mass of an atom, it includes the mass of both protons and neutrons. Therefore, the number of protons plus the number of neutrons determines the atomic mass of an atom.
