What observations can you make about the valence electrons in the following columns of the periodic table? -Column 1:
-Column 2:
-Transition Metal Columns:
-Columns 3–7:
-Column 8:
Answers
Answer:
Column 1. They have one valence electron
Column 2. They have 2 valence electrons
Transition metal column. Variable oxidation states
Column 3–7. Valence electron ranges from 3 to 7 electrons
Column 8. Completely filled i.e no valence electron
Explanation:
Final answer:
Each column of the periodic table represents elements with a specific number of valence electrons. Columns 1 and 2 have one and two valence electrons respectively, and are known for their reactivity. Transition metals typically have one or two, Columns 3-7 have 3 to 7, and Noble Gases in Column 8 have a full shell of eight, making them unreactive.
Explanation:
We can categorize columns, or groups, of the periodic table by the number of valence electrons, which are the outermost electrons in an atom that participate in chemical bonding.
- Column 1: These elements, also known as alkali metals, have a single valence electron in their outermost shell. These elements are highly reactive due to their tendency to lose this electron and achieve a stable configuration.
- Column 2: These are the alkaline earth metals, which have two valence electrons. They are less reactive than alkali metals but will still readily lose their valence electrons to achieve stability.
- Transition Metal Columns: These contain transition metals which typically have one or two valence electrons, although this can be more complex due to the filling of inner d orbitals.
- Columns 3–7: Elements in these groups have 3 to 7 valence electrons respectively. Many form covalent bonds by sharing their valence electrons with other atoms.
- Column 8: Known as the Noble Gases, these elements possess a stable full set of 8 valence electrons (except for Helium which has 2). They are very unreactive due to their stable electronic configuration.

The statement which best describes Charles law is: A) If volume increases, temperature increases.
What is Charles law?
Charles law states that when the pressure of an ideal gas is kept constant, the volume of a gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles law is given by this formula;
This ultimately implies that, as the volume of an ideal gas increases, its temperature also increases in accordance with Charles law.

A) If volume increases, temperature increases
The law is V/T, meaning the two values are directly proportional, as one increases, the other increases too.

Answer:
3.79 g of N2.
Explanation:
We'll begin by writing the balanced equation for the reaction.
This is given below:
4NH3 + 3O2 → 2N2 + 6H2O
Next, we shall determine the mass of O2 that reacted and the mass of N2 produced from the balanced equation.
This is illustrated below:
Molar mass of O2 = 16x2 = 32 g/mol
Mass of O2 from the balanced equation = 3 x 32 = 96 g
Molar mass of N2 = 2x14 = 28 g/mol
Mass of N2 from the balanced equation = 2 x 28 = 56 g
Summary:
From the balanced equation above,
96 g of O2 reacted to produce 56 g of N2.
Finally, we shall determine the mass of N2 produced by reacting 6.50 g of O2.
This can be obtained as follow:
From the balanced equation above,
96 g of O2 reacted to produce 56 g of N2.
Therefore, 6.50 g of O2 will react to produce = (6.50 x 56)/96 = 3.79 g of N2.
Therefore, 3.79 g of N2 were obtained from the reaction..
