Across the periodic table do the elements become more or less metallic?

in groups, as we go down metallic characteristics increases but in periods as we go left to right metallic characters decreases because non-metals are being introduced.
i hope it helped!

∙ 12y agoThe elements in the top right corner of the Periodic Table are the most nonmetallic elements, while the elements in the bottom left hand corner are the most metallic elements. Therefore, the elements at the top of the table within the p-block elements are less metallic than those at the bottom.

What is the trend in metallic character going from left to right across a period in the periodic table?
the metallic character increase down the group as the size of atom increase down the group so the electron in outer most shell r more free to move
What characteristics is shared by elements in the same period?
Elements in the same period have the same number of electron shells, moving across a period (progressing group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.

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
Do metals become more reactive as you move from left to right across the periodic table?
In the alkali metals and the alkaline earth metals (groups IA and IIA on the periodic table), all increase in reactivity as one goes down the columns. These elements react by loaning out electrons, and it is easier to loan out an electron if the valence band where that lone electron (group IA) or two (group IIA) hangs out is farther from the nucleus and is screened by other (more) electrons in lower bands. The elements farther down the columns are more reactive because they can more easily loan out electrons. Just as an aside, one might expect that the elements that borrow electrons might be better able to do that if there was less electron screening, right? And that would suggest that the elements higher in the columns of the groups that are seriously interested in borrowing electrons (think group VIIA) would be more reactive than the lower ones, wouldn't it? Maybe that's why fluorine is called the hungry wolf of the periodic table.
Is the reactivity of the metal elements generally increase as you move from left to right across the periodic table true or false?
False,reactivity of elements generally decreases from left to right.As free electrons become less,reactivity decreases.So the given statement is false.
Across the periodic table the properties of elements become WHAT?
across a periodic table, the properties of elements become less metallic and more nonmetallic
What elements in a period on the periodic table become?
more metallic moving from left to right
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.
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
What is the trend in metallic character going from left to right across a period in the periodic table?
the metallic character increase down the group as the size of atom increase down the group so the electron in outer most shell r more free to move
What characteristics is shared by elements in the same period?
Elements in the same period have the same number of electron shells, moving across a period (progressing group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
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.
Do elements become more or less metalic as you go down a group?
they become more 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.
