Your question: What is another name for a row of elements?

A row of elements is called a period. The atomic number increases from left to right. The period represents an energy level. The number of elements in one period is equal to the number of electrons that the energy level can hold.

What is another name for the rows of the periodic table?

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.

What is a row of elements called?

The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups. … Elements in the periodic table are organized according to their properties.

What is another name for a column of elements?

In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements.

What’s another name for groups of elements?

Answer is: another name for groups of elements is family. There are 18 numbered groups in the periodic table. The elements in a group have similar physical or chemical characteristics and some groups have a specific name, for example group 17 (the halogens).

What do the rows mean on a periodic table?

Each row represents one period; the period number of an element indicates how many of its energy levels house electrons. Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels.

Why are the rows in the periodic table called periods?

The rows on the periodic table are called periods. All the elements in a period have valence electrons in the same shell. The number of valence electrons increases from left to right in the period. When the shell is full, a new row is started and the process repeats.

What is the relationship between elements in a row?

All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, groups of elements in the same column have similar chemical and physical properties, reflecting the periodic law.

What element has properties like Lithium?


Which two elements are in the same period?

Elements that are in the same period have chemical properties that are not all that similar. Consider the first two members of period 3: sodium (Na) and magnesium (Mg). In reactions, they both tend to lose electrons (after all, they are metals), but sodium loses one electron, while magnesium loses two.

What are 3 elements that have similar properties?

Magnesium, strontium, and barium belong to group 2A of the periodic table. These have two valence electrons in their outermost shell. So these three elements have similar chemical properties.

What element is in Group 13 and Period 2?

The boron family contains elements in group 13 of the periodic talbe and include the semi-metal boron (B) and the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl).

What is the name of column 17 on the periodic table?

The halogen elements are the six elements in Group 17 of the periodic table. Group 17 is the second column from the right in the periodic table and contains six elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (As), and tennessine (Ts).

What are the Group 3 elements called?

Group 3A (or IIIA) of the periodic table includes the metalloid boron (B), as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). Boron forms mostly covalent bonds, while the other elements in Group 3A form mostly ionic bonds.

What is another name for inner transition metals?

The inner transition elements are sometimes called the f-block elements, since in this region the f-orbitals are being filled in.

What are the 8 groups in periodic table?


  • Group 1: alkali metals, or lithium family.
  • Group 2: alkaline earth metals, or beryllium family.
  • Group 3: the scandium family.
  • Group 4: the titanium family.
  • Group 5: the vanadium family.
  • Group 6: the chromium family.
  • Group 7: the manganese family.
  • Group 8: the iron family.
