Here are the answers to your questions:
-
Which subatomic particles are used to calculate the atomic number? Which subatomic particles are used to calculate the mass number?
Answer: The atomic number is calculated using the number of protons in an atom. The mass number is calculated by adding the number of protons and neutrons. -
The different rows of the periodic table represent what about the electrons of an atom?
Answer: The different rows (periods) of the periodic table represent the principal energy levels or shells that contain the electrons of an atom. As you move down a row, the number of energy levels increases. -
What is a bond? What are atoms trying to do when they bond?
Answer: A bond is a force that holds atoms together in a molecule or compound. Atoms bond to achieve a more stable electronic configuration, often by filling their outer electron shell. -
Where on the periodic table does it tell you the number of valence electrons an element has?
Answer: The number of valence electrons can often be determined from an element's group number in the periodic table. For main group elements (Groups 1, 2, and 13-18), the group number corresponds to the number of valence electrons. -
The atoms on the periodic table are organized by an increasing number of what?
Answer: The atoms on the periodic table are organized by increasing atomic number (the number of protons). -
Why are the Noble gases unreactive?
Answer: The Noble gases are unreactive because they have a complete valence shell of electrons, which makes them stable and less likely to form bonds with other elements. -
Where on the periodic table do you find elements that are reactive because they have high electronegativity?
Answer: Elements that are reactive due to high electronegativity are typically found on the right side of the periodic table, particularly the halogens (Group 17) and some of the nonmetals. -
Which elements are the best conductors: Metals or nonmetals?
Answer: Metals are the best conductors of electricity and heat compared to nonmetals. -
Where are nonmetals located on the periodic table?
Answer: Nonmetals are located on the right side of the periodic table, to the right of the metalloids. -
Why is Hydrogen’s Mass Number the same as its Atomic Number?
Answer: Hydrogen's mass number is the same as its atomic number because the most common isotope of hydrogen has one proton and no neutrons, making both values equal to 1. -
Ionic bonds are most likely to occur when the number of valence electrons is close to what numbers?
Answer: Ionic bonds are most likely to occur when the number of valence electrons is close to 1 (for metals) or 7 (for nonmetals). -
How many valence electrons could an atom of Carbon accept in a bond?
Answer: An atom of Carbon can accept up to 4 valence electrons in a bond, as it has 4 valence electrons and can form a total of 4 bonds. -
What compound is present in every –Hydroxyl compound?
Answer: The compound present in every -hydroxyl compound is hydroxyl (–OH). -
What is the difference between polar and nonpolar Covalent bonds?
Answer: Polar covalent bonds occur when electrons are shared unequally between atoms, resulting in a partial positive and partial negative charge. Nonpolar covalent bonds occur when electrons are shared equally or nearly equally between atoms, resulting in no significant charge difference. -
When using the “ball and stick” drawing method of drawing a compound, which element usually goes in the center of the model?
Answer: In the "ball and stick" model, the central atom is usually the least electronegative element or the atom that can make the most bonds. -
Which elements are the most reactive and why?
Answer: The most reactive elements are typically the alkali metals (Group 1) and the halogens (Group 17) because they have one valence electron (alkali metals) or need one additional electron (halogens) to achieve a stable electron configuration. -
How do you determine the number of neutrons in an element?
Answer: To determine the number of neutrons in an element, subtract the atomic number (number of protons) from the mass number: Neutrons = Mass Number - Atomic Number.
