What are the horizontal lines on the periodic table called?
The horizontal rows are called period and the vertical columns are called groups. What element is soft and shiny? Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Why is the periodic table arranged in columns?
Why are the elements on the periodic table grouped in columns the way they are? The columns of the table represent groups, or families, of elements.The elements in a group often look and behave similarly, because they have the same number of electrons in their outermost shell — the face they show to the world.
Are columns vertical or horizontal?
KEY DIFFERENCES A row is a series of data put out horizontally in a table or spreadsheet while a column is a vertical series of cells in a chart, table, or spreadsheet. Rows go across left to right. On the other hand, Columns are arranged from up to down.
Which group is the 2 column of periodic table?
These elements (except hydrogen) are known as alkali metals, and they all have similar chemical properties. The elements in group 2 (the second column) form compounds consisting of one atom of the element and two atoms of hydrogen: These are called alkaline earth metals, with similar properties among members of that group.
What are the vertical columns on the periodic table called quizlet?
The vertical columns in the periodic table are called groups. Elements in the same group have similar chemical properties. The group number is the same as the number of electrons in the outer shell of all the elements in the group..
What is vertical column?
The vertical columns in the modern periodic table are known as groups and the horizontal rows are known as periods. There are 7 periods and 18 groups in the modern periodic table.
What is a vertical row on the periodic table?
The periodic table is composed of vertical columns called groups and horizontal rows called periods. The periodic table is divided into groups (vertical columns) and periods (horizontal rows). Elements are placed in the periodic table in order of increasing atomic number (Z). Groups (or families) are vertical columns.
How many vertical columns are in the periodic table?
18 vertical columnsThe elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups. Groups are labeled at the top of each column.
Why distillation column is vertical?
The internal separation wall prevents lateral mixing of liquid and vapour in the central part of the column, forming there separate feed and outlet sections. In the presence of a vertical partition, 3 or 4 pure fractions can be obtained in a single distillation step.
What's the difference between horizontal and vertical?
Anything parallel to the horizon is called horizontal. As vertical is the opposite of horizontal, anything that makes a 90-degree angle (right angle) with the horizontal or the horizon is called vertical. So, the horizontal line is one that runs across from left to right.
Which way is vertically?
up and downThe terms vertical and horizontal often describe directions: a vertical line goes up and down, and a horizontal line goes across. You can remember which direction is vertical by the letter, "v," which points down.
What do you mean by columns?
Definition of column 1a : a vertical arrangement of items printed or written on a page columns of numbers. b : one of two or more vertical sections of a printed page separated by a rule or blank space The news article takes up three columns.
Answer
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.

Which atom has more protons, Li or F?
Li, both Li and F have two energy levels, F has more protons which increases coulombic attraction and decreases the size of the atom.
What happens when the number of energy levels remain constant?
With the number of energy levels remaining constant and increase in protons across a period leads to an increase in coulombic attraction this causes the atoms to squeeze in tighter resulting in a decrease in atomic size
