Q: what are the groups on a periodic table
A: The **groups** on a periodic table are the vertical columns. There are 18 groups, numbered 1-18. Elements within the same group typically have similar chemical properties due to having the same number of valence electrons.
Q: what are the horizontal rows called in the periodic table
A: The horizontal rows in the periodic table are called **periods**.
Q: what are the horizontal rows on a periodic table called
A: The horizontal rows on a periodic table are called **periods**.
Q: what are the metal elements in the periodic table
A: The metal elements in the periodic table are characterized by properties such as conductivity (of heat and electricity), malleability (can be hammered into shape), ductility (can be drawn into wires), and a shiny luster. They are located on the left and central parts of the table and include diverse categories like alkali metals, alkaline earth metals, transition metals, lanthanides, actinides, and post-transition metals.
Q: what are the periodic table families
A: Periodic table **families** are the same as **groups** – the vertical columns of elements. Elements within a family share similar chemical properties because they typically have the same number of electrons in their outermost shell (valence electrons).
Q: what are the rows called in the periodic table
A: The horizontal rows in the periodic table are called **periods**.
Q: what does the number mean on the periodic table
A: The most prominent number on an element's box in the periodic table is the **atomic number** (usually at the top), which indicates the number of protons in an atom of that element. This number defines the element. Another key number is the **atomic mass** (usually at the bottom, often a decimal), representing the average mass of the element's atoms. Group numbers (1-18) and period numbers (1-7) also provide organizational context and relate to electron structure.
Q: what element is ag on the periodic table
A: "Ag" on the periodic table is the chemical symbol for the element **Silver**. It is a transition metal with atomic number 47.
Q: what element is au in the periodic table
A: "Au" in the periodic table is the chemical symbol for the element **Gold**. It is a transition metal with atomic number 79.
Q: what elements on the periodic table are metals
A: The vast majority of elements on the periodic table are metals. They are generally located to the left of the "staircase" line that separates them from nonmetals. This includes well-known metals like iron (Fe), copper (Cu), gold (Au), aluminum (Al), sodium (Na), and many others, encompassing categories like alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides.
Q: what is a column called on the periodic table
A: A vertical column on the periodic table is called a **group** or a **family**.
Q: what is a family in the periodic table of elements
A: A **family** in the periodic table of elements is a vertical column, which is also known as a **group**. Elements in the same family (or group) share similar chemical properties because they typically have the same number of electrons in their outermost energy level (valence electrons).
Q: what is a family periodic table
A: A **family** in the periodic table refers to a **group**, which is a vertical column of elements. Elements within the same family share similar chemical characteristics, largely due to having the same number of valence electrons.
Q: what is a horizontal row called on the periodic table
A: A horizontal row on the periodic table is called a **period**.
Q: what is a horizontal row in the periodic table called
A: A horizontal row in the periodic table is called a **period**.
Q: what is ag periodic table
A: "Ag" on the periodic table is the chemical symbol for **Silver**. It is a transition metal with atomic number 47.
Q: what is as in the periodic table
A: "As" is the chemical symbol for **Arsenic** in the periodic table. It is a metalloid (or semimetal) located in Group 15, with atomic number 33.
Q: what is au in the periodic table
A: "Au" in the periodic table is the chemical symbol for **Gold**. It is a transition metal with atomic number 79. The symbol 'Au' comes from its Latin name, 'aurum'.
Q: what is au on the periodic table
A: "Au" on the periodic table is the chemical symbol for **Gold**. It is a transition metal found in Group 11, with atomic number 79.
