What are the horizontal rows on the periodic table?
What are the horizontal rows on the periodic table?
The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups.
How is the periodic table arranged horizontally?
In the periodic table, the elements are arranged in horizontal rows called periods (numbered in blue) and vertically into columns called groups. For example, elements in each Group of the periodic table (each vertical column) will share many of the same chemical properties.
Is a period a horizontal row on the periodic table?
A period is a horizontal row of the periodic table. There are seven periods in the periodic table, with each one beginning at the far left. A group is a vertical column of the periodic table, based on the organization of the outer shell electrons. There are a total of 18 groups.
What are the horizontal left to right rows called on the periodic table?
The elements are arranged in seven horizontal rows, in order of increasing atomic number from left to right and top to bottom. The rows are called periods, and they are numbered from 1 to 7.
What is the last row of the periodic table called?
noble gases
What are the top ten elements in the human body?

- Carbon. Chemical symbol C; 18% of the human body weight.
- Hydrogen. Chemical symbol H2; 10% of the human body weight.
- Nitrogen. Chemical symbol N2; 3% of the human body weight.
- Calcium. Chemical symbol Ca; 1.5% of the human body weight.

Why are transition elements called that?
The d-block elements are called transition elements because they exhibit transitional behaviour between s-block and p-block elements. Their properties are transitional between highly reactive metallic elements of s-block which are ionic in nature and the elements of p-block which are covalent in nature.
What is the most electromagnetic element?
fluorine
What is the difference between representative elements and transition elements?
The representative elements are elements where the s and p orbitals are filling. The transition elements are elements where the d orbitals (groups 3–11 on the periodic table) are filling, and the inner transition metals are the elements where the f orbitals are filling.
What is the difference between transition elements and D block elements?
The main difference between d block elements and transition elements is that d block elements have either completely or incompletely filled d orbitals whereas transition elements have incompletely filled d orbitals at least in one stable cation that they form.
What is another name for representative elements?
Another name for the representative elements are the Group A elements or the main group elements.

What are the elements 57 71 called?
Lanthanoid, also called lanthanide, any of the series of 15 consecutive chemical elements in the periodic table from lanthanum to lutetium (atomic numbers 57–71).
What is Group 4 on the periodic table called?
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member. All the group 4 elements are hard, refractory metals.
What is the smallest group on the periodic table?
helium
What are the four elements of the periodic table?
Last December, four new elements—with atomic numbers 113, 115, 117, and 118—earned their spots on the periodic table.
What are the Group 6 elements called?
Group 6, numbered by IUPAC style, is a group of elements in the periodic table. Its members are chromium (Cr), molybdenum (Mo), tungsten (W), and seaborgium (Sg). These are all transition metals and chromium, molybdenum and tungsten are refractory metals.
