How does density change as it goes down the group and across the periods?

Among gaseous and liquid nonmetals, as atomic number increases, London dispersion forces increase with the number of electrons, resulting in higher polarity and intermolecular attraction. Therefore, density generally increases as atomic number increases.
The majority of metals have higher densitiesthan the majority of nonmetals. The high density of most metals is due to the tightly packed crystal lattice of the metallic structure. The strength of metallic bonds for different metals reaches a maximum around the center of the transition metal series, as those elements have large amounts of delocalized electrons in tight binding type metallic bonds.
However, other factors (such as atomic radius, nuclear charge, number of bonding orbitals, overlap of orbital energies, and crystal form) are involved as well.

∙ 13y agoDensity is going UP when going down in the group
Density is going UP first and then going DOWN in the second part of the period when travelling from left to right, being at maximum at about group 11 (Cu) to 8 (Ru, Os).

How does density change by going down the periodic table?
Atomic radius are increase so density change by going down the periodice table
What is the name of a row going across the periodic table?
A row of elements is known as a Period, while a column is known as a group, or family.

How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
How does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
Do element properties change as you move across a period or whithin a group?
Yes, it is true, the properties of elements change in groups and periods.

When you read across a row on the periodic table what happens?
Periods (across the periodic table) have increasing atomic mass. Groups (down the table) have similar properties and reactive natures.
How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
On a periodic tableprotons increase?
As you move from left to right on rows, or across periods and top to bottom, or down a group, the number of protons increases.
Are columns of elements called periods?
No,Each of the columns in a periodic table represents a group.
How does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
What are periods and groups?
Elements in the periodic table are arranged in periods (rows) and groups (columns). Atomic number increases as you move across a row or period. The period number of an element signifies the highest unexcited energy level for an electron in that element. Elements within a group share several common properties. Groups are elements have the same outer electron arrangement. The outer electrons are called valence electrons.
What is the difference between a period and a group on the periodic table?
Periods on the periodic table go across and are based on the number of unexcited electrons increasing as you read across. Groups on the periodic table are read down the table and share the same number of valence electrons.
How does the atomic number change across a column of the periodic table?
Columns are vertical, so you are referencing a group of elements. The atomic number increases as you descend from top to bottom. Rows are horizontal, which references the periods. The atomic number increases as you go from right to left.
