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 does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
How does the number of valence electrons change as you go across the 2nd period of the periodic table?
the no. of electrons increses
Do valence electrons increase or decrease across the row of tables?
They increase from left to right.
What do you notice about the number valence electrons?
left to right across on a row or a periodic table
What happens to valence electrons as you move across the row?
The number of valence electrons increases.
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 does the number of valence electrons for elements across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
Elements across a series have the same number of?
They don't have the same number. that's what makes thme all different
How does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
How does the number of valence electrons change as you go across the 2nd period of the periodic table?

What is the trend of valence electrons across each period?
The number of valence electrons increases as you go across a period. For example in period 2 the number of valence electrons rises from 1 in Li up to 8 in neon.
Do valence electrons increase or decrease across the row of tables?
They increase from left to right.
What do you notice about the number valence electrons?

How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
What happens to the reactivity of metals from left to right across the perriodic 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.
As you move across a period elements have the same number of?
Electron shells
