Where and what side on the periodic table is more active?
The most active elements on the periodic table are found on the left side and in the bottom rows, specifically the alkali metals (Group 1) and the alkaline earth metals (Group 2). Alkali metals, such as sodium and potassium, are highly reactive, particularly with water, and their reactivity increases as you move down the group. In contrast, halogens (Group 17) on the right side of the table are also very reactive, with reactivity decreasing down the group. Overall, reactivity trends vary depending on whether the elements are metals or nonmetals.
How would Dmitri Mendeleev would of understood how halogens and alkali metals are so reactive?
Dmitri Mendeleev would have understood the reactivity of halogens and alkali metals in terms of their electron configurations and positions in the periodic table. Alkali metals, with one electron in their outer shell, readily lose that electron to achieve a stable noble gas configuration, making them highly reactive. Conversely, halogens, with seven electrons in their outer shell, are eager to gain one electron to complete their octet, which also contributes to their high reactivity. Mendeleev's arrangement of the periodic table highlighted these trends, illustrating the relationship between atomic structure and chemical behavior.
How many tables are in the periodic table?
The periodic table is just ONE table. There are not sub-tables. The periodic table is divided into periods (the horizontal rows of the table) and groups (the vertical columns). As you move horizontally across the table, an increase is the atomic number is seen, along with trends in acidity, bonding behavior, and reactivity. The groups are arranged to contain elements that have similar properties. For example, Group 1 is called the alkali earth metals group; all are light, highly reactive metals. Many more trends and groupings exist.
What elements in the tall columns periodic table called?
The tall columns in the periodic table are called groups or families. Elements in the same group share similar chemical properties and have the same number of valence electrons. For example, Group 1 contains alkali metals, while Group 17 consists of halogens. Each group typically exhibits trends in reactivity and other characteristics down the column.
Why was the periodic table written?
The periodic table was created to organize the elements based on their atomic structure and properties. It helps scientists understand the relationships between different elements and predict their behavior. The table's layout also allows for patterns and trends to be easily identified.

What are the answers to the periodic table and reactivity crossword?
To provide accurate answers, I would need specific clues or questions from your periodic table and reactivity crossword. However, common themes in such puzzles might include element symbols, reactivity trends (like metals vs. nonmetals), or specific elements known for their reactivity, such as alkali metals (like sodium or potassium) and halogens (like chlorine). If you provide more details or clues, I can help you better!

What are the trends in reactivity with HCl in alkaline earth metals?
The Alkali Earth metals are found in group 1 and 2 of the periodic table. When reacted with hydrochloric acid, the vigour of the reactions increases going down the groups. So Lithium will react gently with hydrochloric acid whilst Caesium will react explosively. The same applies for the group 2 metals. Generally speaking, Alkali metals will react with hydrochloric acid: X + HCl -----------> XCl + H2 Where X is the alkali metal and will react to form a chloride
What periodic trends are most significant in metals?
Metals form cations. They loose electrons.
What elements in the tall columns periodic table called?
The tall columns in the periodic table are called groups or families. Elements in the same group share similar chemical properties and have the same number of valence electrons. For example, Group 1 contains alkali metals, while Group 17 consists of halogens. Each group typically exhibits trends in reactivity and other characteristics down the column.

What are the three metal the would behave in a similar way?
The three metals that would behave similarly are lithium, sodium, and potassium. These alkali metals are in the same group of the periodic table and exhibit comparable chemical properties, such as high reactivity, especially with water, and the formation of strong bases. Their single valence electron leads to similar trends in ionization energy and electronegativity. As a result, they participate in similar types of reactions and form analogous compounds.
How does the solubility changes as you go to lower rows in the periodic table for alkali and alkaline earth metals?
As you move down the periodic table, the solubility of alkali metals (Group 1) generally increases due to their decreasing lattice energy and increasing hydration enthalpy, making their compounds more soluble in water. In contrast, for alkaline earth metals (Group 2), solubility trends can vary; while the solubility of some sulfates decreases down the group, most hydroxides and carbonates become less soluble. Overall, alkali metal compounds tend to be more soluble compared to those of alkaline earth metals.
What is a regular and repeating pattern in Mendeleev's table?
In Mendeleev's periodic table, a regular and repeating pattern is the arrangement of elements in order of increasing atomic mass, which reveals periodic trends in their chemical and physical properties. Elements with similar properties are grouped together in vertical columns, known as groups or families. For example, elements in Group 1 (alkali metals) exhibit similar reactivity and characteristics. This periodicity reflects the underlying structure of atoms and their electron configurations.
Where is the most active solid in a period found?
The most active solid in a period is typically found in the alkali metals group, specifically in the first column of the periodic table. These elements, such as lithium, sodium, and potassium, are highly reactive, especially with water and air, and their reactivity increases as you move down the group. In contrast, the most active solid nonmetals, like iodine, are found in the halogens group, which is the second-to-last column. Overall, the reactivity trends are influenced by atomic structure and electron configuration.
