Q1Refer to the table of elements below. Which element, essential for building bone tissue in the human body, has an atomic number of 20? Element Atomic Number Hydrogen 1 Carbon 6 Oxygen 8 Calcium 20
Show answer
✓ Correct answer: Calcium
The element with an atomic number of 20 is Calcium. Calcium is essential for building and maintaining bone tissue in the human body.
Q2The main components contained within the nucleus of a human body cell are:
Show answer
✓ Correct answer: DNA and proteins
The nucleus of a human body cell houses DNA (deoxyribonucleic acid) which contains genetic instructions, and proteins which help in maintaining its structure and regulating access to the DNA.
Q3In the context of human physiology, which category would a pure sample of oxygen atoms used for cellular respiration belong to?
Show answer
✓ Correct answer: an element
Oxygen, when consisting of a pure sample of its atoms, is classified as an element because it is made up of only one type of atom. In human physiology, this distinction is important for understanding respiratory processes.
Q4In the structure of a water molecule, which subatomic particle of an oxygen atom determines that it is oxygen?
Show answer
✓ Correct answer: Protons
An oxygen atom is defined as such because it has 8 protons. Protons are positively charged and have a significant role in defining the atomic number of an element, thereby determining its identity.
Q5Examine the following data on subatomic particles. Which particle defines the identity of an element by its number and possesses a positive charge? Particle Charge Mass (amu) Electron Negative 0.0005 Neutron Neutral 1 Proton Positive 1
Show answer
✓ Correct answer: Proton
The number of protons in an atom's nucleus defines the identity of the element. Protons have a positive charge and a mass of one atomic mass unit, contrary to electrons which are negatively charged and neutrons which are neutral.
Q6What is an atomic orbital?
Show answer
✓ Correct answer: The region around an atom's nucleus where electrons are likely to be found.
An atomic orbital is a region of space around the nucleus where there is a high probability of finding an electron. This concept helps explain the distribution of electrons in an atom and their role in chemical bonding and interactions.
