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.
Describe relationships between elements using the periodic table.HELP?
As you go across the periodic table from left the right the metallic nature decreases and the non- metallic nature increase. As we go down the group of atoms on the metal side the atoms get bigger and being metals loose electrons more easily therefore become more reactive As we go the group of atoms on the non metal side the atoms get smaller and are less likely for electrons to be gained
In terms of the periodic table is there a gradual or abrupt change when it comes to covalent bonds?
There is a gradual change in the nature of covalent bonds as you move across a period on the periodic table. Covalent bonds become more polar and less covalent as you move from left to right across a period due to increasing electronegativity of the elements.
Is the reactivity of the metal elements generally increase as you move from left to right across the periodic table true or false?
True. Generally, the reactivity of metal elements increases as you move from left to right across the periodic table. This is because as you move towards the right, the elements have fewer electrons in their outer shell, making them more likely to lose electrons and react with other elements.
What characteristics is shared by elements in the same period?
Elements in the same period share the same number of electron shells, or energy levels. This means they have similar atomic sizes and exhibit similar chemical properties due to their outermost electron configuration.
Across the periodic table the properties of elements become WHAT?
Across the periodic table, the properties of elements become more predictable and show periodicity, meaning they exhibit regular patterns in their physical and chemical properties. This is due to the arrangement of electrons in the atom and the increasing number of protons in the nucleus as you move from left to right across the table.
What elements in a period on the periodic table become?
more metallic moving from left to right
Do element become more metallic across each period?
No, elements become less metallic across periods. Periods are horizontal rows within the periodic table, and read left to right. The far right elements are called non-metals, and the far left elements are called metals. In between these two groups are a few metalloids - elements that have characteristics of both metals and non-metals. A period looks like this: Metals --> Metalloid --> Non-metals
Does metal on the periodic table become more metallic at the bottom of the table?
yes, elements get more metallic the further down they go.
What conclusion can be drawn about the relationship between the arrangements of elements on the periodic table and the patterns observed in there properties?
The arrangement of elements on the periodic table reflects their atomic structure and properties, with elements grouped by similar chemical behaviors and characteristics. This organization reveals periodic trends, such as electronegativity, atomic radius, and ionization energy, which vary systematically across periods and groups. As you move from left to right, elements typically become less metallic and more non-metallic, with increasing electronegativity. Therefore, the periodic table serves as a valuable tool for predicting and understanding the chemical properties of elements based on their positions.
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.
How do the elements in the period you choose compare?
In a period of the periodic table, elements have the same number of electron shells but different numbers of electrons in their outer shell. As you move across a period from left to right, the number of protons and electrons increases, causing elements to become more electronegative and decrease in atomic radius. Additionally, elements within a period show a trend of increasing metallic to non-metallic properties.
As you go down a group the elements generally become more or less metallic?
As you go down a group on the periodic table, elements generally become more metallic. This is because the number of electron shells increases down the group, leading to greater distance between the nucleus and the outer electrons. As a result, the outer electrons are less strongly attracted to the nucleus, making the elements more metallic.
Do elements become more metallic when you go down groups?
an element becomes more metallic as you travel down a group. it becomes less metallic as you travel from left to right across a period.
Are there are more metallic elements than non metallic elements?
Yes. There are 17 non-metal elements (assuming you count hydrogen which is normally a gas, but can under extreme pressure and low temperature become metallic) There are 6 metalloid elements (t least they are usually classified) There are 84-94 metallic elements in the periodic table (about 10 have only been synthesized on the order of a few atoms or only hypothesized so definitively declaring them metals might not be possible).
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.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
