first, consider the two elements: Neon and Sodium.
now read about their characteristics.
Moving from the element with atomic number 10 to atomic number 11 on the periodic table, there is a change in reactivity. In three to five sentences, identify the direction of the change, and give two reasons for the change.

Here is a start.
Ne has its outside shell full of electrons; therefore, its reaction with other elements is minimal if at all. Na, the next element, has 1 more proton and 1 more electron. More importantly that added electron is in the outside shell. It can fill that shell by ADDing 7 more electrons or LOSing the one electron. Obviously, it loses the one electron and it does so with gusto which makes Na a very reaction element while Ne is not reactive at all. Now follow oobleck's instructions, add what you read to what I've written,then summarize all of it in your own words.

My answer:
Neon (Ne) has an atomic number of 10, and sodium (Na) has an atomic number of 11. Neon has its outside shell full of electrons; therefore, it does not react with other elements. Sodium has 1 more proton and 1 more electron. That added electron is in the outside shell, making it a valence electron. It can fill that shell by losing the one electron which makes Na a very reactive element while Ne is not reactive.

Demonic sin . was it right ?
So today I got a whole test wrong because my teacher thought I cheated on here. Even though there is no tie between the answers. He can go suck a chicken strip #rude
I’m taking the same test right now and I don’t normally use this site unless I’m really stuck, thank you Drbob222 and oobleck for helping!!!!
Thank for the help
It is an Honor Code violation to use internet resources, such as this website, on your test essay questions. Doing so will result in a zero on the essay question and a discipline report.
Seger you know we wouldn't remember this anyways, nobody cares about this, we are just pressured to get good grades by our parents so we have to pretend to care. Let people who need help and aren't getting it from their teachers get some assistance on stuff they are struggling with.
What is nitrogen's atomic number?
A. 7
B. 14
C. 15
D. 21
A. 7
B. 14
C. 15
D. 21
Ari, your answer is A. 7. I know im late anyways XD
lol me finding my sissys answer from last year and rewording itXD
Segar - maybe teach your class better so we don't need to help each other outside of your class. Go play somewhere else where you are actually wanted.
I'm about to have Mrs. Seger's name revert back to Ms. Seger, If you know what I mean
Mrs. Seger if we really cared and could remember id like to think we would not be on this site
(Question) If only an element’s atomic number and weight are provided, what other atomic information can be determined for a neutral atom?
(Answer) the number of protons, electrons and neutrons
(Question) What quality differentiates hydrogen (H) from the other elements in group 1, the alkali metals?
(Answer) It is a non-metal.
(Question) On which atomic property proposed by Henry Moseley is the current periodic table of the elements based?
(Answer) atomic number
(Question) You plan to pass alpha particles through a field that contains a consistent type of particle. Which configuration will result in the largest deflection of alpha particles?
(Answer) low-energy alpha particles passing through a field of high mass-number-particles
(Question) Which statement about metals and nonmetals is correct?
(Answer) Metals can be hammered into thin sheets, and nonmetals are brittle.
(Question) Based on properties of elements in the periodic table, which element is the best conductor of thermal energy?

(Answer) silicon (Si)
(Question) Which statement best explains why hydrogen’s atomic number is equal to its mass?
(Answer) Hydrogen does not have any neutrons.
(Question) Which statement correctly compares the valence electrons for atoms of francium (Fr) and barium (Ba)?
(Answer) Francium has fewer valence electrons, but they are in a higher energy level.
(Question) Why are the noble gases the least reactive elements?
(Answer) They have a full valence electron shell.
(Question) Group 2 elements have two valence electrons. Which kind of bond will they most likely form, and why?
