What else can I help you with?
What happens to the trends as you go from left to right on the periodic table?
As you go from left to right of the staircase, the number of electrons on the valence shell increases (not counting the transition element). Anything left of the staircase the elements lose electrons, and anything right of the staircase gains electrons.I hope that helps!!!!!
How do the tendancey to loose electron change as you go from left to right in a period?
The further right you go through a period, the less likely you are to lose electrons. This is because elements have more valence electrons as you go right, and if you have more electrons than you don't you will probably just take an electron. All of this is demonstrated by oxidation numbers.
Do you lose electrons going left to right on the periodic table?
No, the number of electrons increases as you move to the right.
The number of electrons in an atom decreases as you move from left to right in the periodic table?
This is not accurate. The number of electrons in an atom does not decrease as you move from left to right in the periodic table. The number of electrons increases across a period, as you move from left to right, based on the atomic number.
Why does atomic size increase as you go from left to right across a period?
atomic size decreases as we go from left to right. as we go from left to right, the number of protons in the nucleus increases, so the effective nuclear charge increases. due to this the electrons are attracted more towards the nucleus and hence, the size decreases.
What do you notice about the number of valence electrons as you move from left to right across a row or period?
The number of valence electrons increases from left to right across a period.
How and why do the properties of the elements change as one scans across the periodic table from left to right?
How: (I'll let someone else answer that) Why: The number of electrons in the outer "shells" increases as you go from left to right and the total number of protons and electrons increases as you go from left to right and from up to down.
What is the trend for electrons?
As you go across a period; Left to right, the electron affinity increases. As you go down a group; top to bottom, the electron affinity decreases.
What happens to an atom's size as you move from left right across a period?
Atomic Radius Decreases from left to right. From left to right the amount of valence shell electrons increases, maxing out at 8. These valence electrons are pulled by the positively charged nucleus, thus making it smaller from left to right.
How the tendency change to gain electrons from left to right across a period?
The tendency to gain electrons increases from left to right across a period due to increasing effective nuclear charge, which pulls electrons closer to the nucleus, making it easier to attract additional electrons. This trend is due to the increasing number of protons in the nucleus and the decreasing atomic size as you move from left to right across a period.
What happened to the number of valance electrons move from left to right on the periodic table?
the number of valence electrons increases on moving from left to right in periodic table.Group 1 has 1 valence electron and group-18 has 8 valence electrons.
How does atomic number change as you move from left to right?
I'm guessing you are acking Atomic Radius. The atomic radius decreases and you go left to right because the shielding effect from the lower electrons stays almost constent while the elements gain more protons adding to the effective nuclear charge pulling the electrons closer to the nucleus.
