What else can I help you with?
What are the gradual changes in the properties across the row called?
The gradual changes in properties across a row in the periodic table are called periodic trends. These trends include atomic size, ionization energy, electron affinity, electronegativity and metallic character.
What changes from left to right as you move through the groups of periodic table?
Atomic radius increases across a group. Metallic character also increases.
How do elements changes as you across the periodic table?
the number of protons increases
What happen if you move left to right a across a periodic table in metals?
Across a period the metallic character decreases
How do you recognize a periodic trend on the periodic table?
A periodic trend is recognized by observing how a property changes as you move across or down the periodic table. If the property shows a repeating pattern or periodicity, such as consistently increasing or decreasing values at regular intervals, then it is likely a periodic trend. Common examples include atomic radius increasing down a group or ionization energy increasing across a period.
What happens to the metallic character of the element as you go across the periodic table?
The metallic character tends to decrease as you move across the periodic table from left to right. This is because elements on the left side of the periodic table, such as alkali metals and alkaline earth metals, tend to exhibit more metallic properties, while elements on the right side, such as nonmetals, tend to have less metallic character.
What is the trend in metallic character going from left to right across a period in the periodic table?
Metallic character decreases from left to right across a period in the periodic table. This is due to the increasing number of protons in the nucleus, leading to stronger attraction between the nucleus and the outer electrons, resulting in less metallic character.
Where are the metallic character on the periodic table?
Metallic character decreases from left to right across a period and increases from top to bottom within a group on the periodic table. This means that elements in the bottom left corner of the periodic table (such as alkali metals) exhibit high metallic character, while elements in the top right corner (such as noble gases) exhibit low metallic character.
Does atomic radius decrease and metalic character increase from left to right on the periodic table?
Metallic character decreases as you go across any single period of the Periodic Table. This is because metals are characterized by their ability to lose electrons to form cations; the easier it is to do so, the more reactive a metal is. Non-metals are characterized by their ability to gain electrons to form anions; the easier to do so, the more reactive a non-metal is. As you go across any single period, elements gain an extra valency electron. This makes it harder and harder for those elements to lose their valency electrons, thus becoming more and more non-metallic.
How will the tendency to gaining electrons changes as you move from right to left in periodic table?
as you move across a period, you are more and more likely to gain electrons
What are some good questions about the periodic table?
Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
How does one recognize a periodic trend on the periodic table?
one should look for predictable changes and patterns
