look at any Periodic Table and you will see that elements are arranged from left to right and top to bottom in order of increasing atomic number.
What else can I help you with?
When you move from left to right on the periodic table what are some of the major changes?
When you move from left to right on the periodic table, the atomic number of the elements increase.
As you move from left to right in a row of the periodic table the electronegativites tend to what?
Increase
Does the atomic structure increases by one as you move left to right in the periodic table?
The number of protons and electrons increase by one from left to right.
Does electronegativity increase in periodic trend?
Yes, as you move from left to right across the period.
What do you notice about the atomic masses as move from the left to the right on periodic table?
As you move from left to right on the periodic table, the atomic masses generally increase. This is because the number of protons and neutrons in the nucleus of the atom also increases as you move across a period.
Do elements on the periodic table increase in electronegitivity as you go left to right or up and down?
Electronegativity increases as we move from left to right on the periodic table.
Why do faster moving particles or hot particles increase the rate of a reaction?
it move
What major change occurs as you move from left to right on the periodic table?
More subatomic particles, more mass
When you move across the periodic table from left to right what happens to the number of protons contained by each element?
the numbers increase (going right) and decrease (going left)
What is the button used to move the contents of a cell to the left three spaces?
INCREASE INDENT -- You can move contents of a cell by right-clicking on the right border of the cell and dragging to where you want.
What happens to particles in a substance when its heated or cooled?
In a solid, the particles start to vibrate a lot.In a liquid, the particles begin to move around faster and faster.In a gas, the particles move extremely fast through the air.
Does the speed of the wave increase as you move from left to right on the electromagnetic spectrum?
No. As the radiation frequency moves from left to right in the frequency spectrum, the wave speed is the same in a certain medium -- in vacuum, it is 3E8 m/s. The energy increases with frequency, though.
