As you move from left to right across the periodic table elements become?
The periodic table is arranged such that elements with the same number of valence electrons share a column. Valence electrons are those in the outermost shell. The elements at the far left of the table (hydrogen, lithium, sodium, etc) have only one Valence electron, which makes them more prone to reaction than the "Noble Gases" (Helium, Neon, Argon, etc) which have a full Valence shell. For more information, you can visit "http://en.wikipedia.org/wiki/Valence_electron".
How the atomic structure of the elements change as you go across the periodic table from left to right across a period?
As you go from left to right, the elements become less metallic and more nonmetallic.
larger and more electronegative
No, metals become less reactive as you move from left to right across the periodic table.
Elements become less reactive as you move from left to right across the periodic table. This is due to how many valence electrons (outer-most electrons) the element has; the less valence electrons, the more reactive the element.
What is the trend in metallic character going from left to right across a period in the periodic table?
The far left side of the Periodic Table of the Elements are the metals. Traversing the Table from left to the right, the middle becomes the transition metals. The far right become the gases.
The periodic table of elements is the arrangement of elements according to atomic number increasing from left to right across rows of the table.
Across a period the atomic size decreases. Hence elements in the right side of the periodic table have small size / radii.
What happens to the reactivity of elements in groups labeled A as 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.
The atomic radius decreases from left to right.
On the periodic table of elements, electronegativity increases as you move left to right across a period.
Is the reactivity of the metal elements generally increases as you moves from left to right across the periodic table?
No, right to left.
How do the metallic properties of the elements change as you move from left to right on the periodic table?
Metallic properties of the elements decrease as you move from left to right across a period.
As you move across a period of the periodic table from left to right what happens to the elements electronegativity?
from metals to non metals
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
They become more stable.
The elements lose valence electrons
It decreases on going from left to right
The metals are on the left side of the periodic table. All of groups I & II, and all but one of the elements in group III are metals; also some elements in groups further to the right. The atomic weight is increasing.
more metallic moving from left to right
The periodic table contains the metallic elements in the left side and the non metals to the right. The metals are tending to give away electrons whereas the non metals prefer to withdraw them. So, the electronegativity of elements increase from the left to the right. Fluorine, one of the rightmost elements have the highest electronegativity among all the elements in 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.
Is it true that the chemical reactivity of metals trends to increase from left to right across the periodic table?
Yes. Elements are more likely to recieve electrons during a reaction if they are farther to the right on the periodic table.
Ti. Going left to right across a period on the periodic table, the elements get smaller. Also, going top to bottom in a group, the elements get smaller. Ti is above Zr in the periodic table.
Across the period (left to right), the elements tend to change from solids (metals) to gases (non metals).
The Elements on the far right side of the Periodic Table of the Elements are known as the Nobel Gasses.
These are the patterns of the periodic table across the period. 1. The atomic radius reduces as we move across a period from left to right, 2. The ionization energy increases as we move across a period. 3. The electron affinity decreases as we move across a period. Learning them enables us to have a clear view of elements in the periodic table.
This is because ionization energy values for the elements rise as we move across the periodic table, and nonmetals are located to the far right. As we move down a group, metals become more reactive.
The elements on the right side of the periodic table are gases.
What are the trends among the elements for atomic size as you to across a period from left to right?
Moving left to right on the periodic table shows a decreasing trend in the atomic radius.
As you move left to right across a period, the size of the nuclei decreases, and the ionization energy also decreases. The number of electrons and the number of electron shells increases.
There is a thing called a step which goes from under Bromine, across, one down, across.... until you reach the bottom. The elements to the left of the step are metals and the elements to the right are non-metals :)
The elements of the periodic table increase in atomic number as you move across and down. This indicates more protons, and a larger atomic nucleus. The number of electron shells increases as well, with elements with filled valence shells at the right (noble gases). Also, generally elements become less reactive as it moves from the left to the right. As elements go from left to right across the periodic table, each element has one more… Read More
Elements on the very right column of the periodic table are called the noble gases. These gases are not very reactive.
There is one more proton in every element as you go right, and provided there are no ions there is one more electron
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!
The number of valence electrons generally increase from left to right across the periodic table. The elements in group 1 have one valence electron. The elements in group 18 have eight valence electrons.
The elements located on right side of periodic table are non metals. They have acidic property.
the elements on the left side are most reactive. reactivity decreases as you move to the right. the noble gases (last group) are least reactive.
Across the period, size decreases, the ionization increases, electronegativity increases, metallic character decreases, non-metallic character increases.
What trend is generally observed in electronegativity going across the periodic table from left to right?
From left to right and into the upper corner of the periodic table electronegativity increases. Fluorine is the most electronegative element, but the elements in group 18 generally have no electronegativity at all.
Describe the changes in properties of the elements as you move from left to right across the periodic table?
Complexity. As you go right, each element gets more complex (the same goes for down).
The elements in the far right column of the periodic table are called Noble Gasses.
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
The staircase elements are metalloids. The elements to its right are non-metals.
Yes. the atomic radii of the elements tend to decrease across the periodic table from left to right (because the pull from the nuclii increases from left to right) and from bottom to top (because the number of electron shells is decreased)
Electronegativity increases as you move across the periodic table from left to right.
Electronegativity increases as you move across the periodic table from left to right.
Elements atomic radii increase in size as they run down the columns of the periodic table or across the periodic table from right to left. So, Al is larger than Cl. XP
