Question complete the diagram below by using arrows, words and or numbers to show how properties of te helements vary across a period.
Electron arrangement left right
1 2 3 4 3 2 1 0
1. loss
of
electrons
2. Energy
needed to
remove an electron
can someone help me with the first one thanks so much
Your diagram may not have turned out right on the board because it doesn't recognie spaces.
Energy needed to remove an electron (the ionization potential) generally is the lowest for group I and increses from left to right in a period. I hope this helps you get started.
Of course! I can help you with the first question. To show how the properties of elements vary across a period in terms of loss of electrons, you can use arrows, words, and numbers as requested. Here's how you can represent the loss of electrons across a period:
1. Start by drawing a horizontal line to represent the period.
2. Write the atomic numbers of the elements in increasing order from left to right along the line.
3. To represent the loss of electrons, you can use arrows to indicate the direction. Arrows pointing to the right indicate an increasing loss of electrons, while arrows pointing to the left indicate a decreasing loss of electrons.
4. Place the arrows above the atomic numbers to indicate how the loss of electrons changes across the period.
For example, let's say we have a period with four elements: Element A, Element B, Element C, and Element D. The atomic numbers of these elements are 11, 12, 13, and 14, respectively.
You would represent the loss of electrons as follows:
11 -> 12 -> 13 -> 14

This diagram shows that the loss of electrons increases from Element A to Element B, then further increases from Element B to Element C, and finally increases again from Element C to Element D.
Remember, this is just an example. You would need to fill in the specific atomic numbers and draw the arrows accordingly for the period you are working with.
