For 10-across, it should be twentytwo. Not thirty-six.

This website is a life saver! It helped make my homework sooooo much easier! Thank you!

Thank you very much i did my h.w so easy thank you

Thanks a lot

thanks, this helped not only make my assignment easier

Helped during homework.

This was such a big help <3

Thank you soooooo much!! I love you dude Yu made my homework so easy XD

Thanks for this i will perfect my Assignment

It’s really a great and useful piece of information. I’m satisfied that you just shared this helpful info with us. Please stay us up to date like this. Thanks for sharing.

Thank u soooo much!!! 🙂 this was homework and I found this site!

Fair Park High School !!!!!!!!!!!!!!!!

thanks that helped a-lot

THANK YOU SO MUCH THIS REALLY HELPED ME AT LEAST I WON’T GET AN F ON THIS ASSIGNMENT

Actually the answer that says “thirtyone” is actually “thirtysix” so if you want to get it right then put down thirtysix because every teacher will tell you its 36.

THANK YOU !

haha my teacher actually lend this to us for homework. Thank you!

You’re the best man!!! We surely will get perfect on our group task!!! I hope I can personally treat you and thank you!!! I’m so, so, so happy!!!! Thank you once again for this!!!

Perhaps including the answers publicly to an assignment is not of the best interest to teachers using this as a QUIZ.

Periodic Table Questions and Answers

The periodic table is an important tool in chemistry, so there are many periodic table questions that people have. Here are some common questions, with answers in simple, down-to-Earth language that you can understand, even if you’re not a scientist.

What Is the Periodic Table?

Of course, the most basic question is “What is the periodic table?” The simple answer is that it is a chart that shows all of the chemical elements and basic facts about them, that orders the elements by increasing atomic number and common properties. The atomic number is the number of protons in every atom of the element. The number of neutrons in the atom changes its isotope, but not its element. Similarly, the number of electrons changes the ion , but not the element.

What Are Groups and Periods in the Periodic Table?

The way the periodic table organizes elements by properties is by putting them in rows, which are called periods, and columns, which are called groups . Elements in a period have the same outer electron shell, which gives them some common characteristics. Elements in a group have number of outer or valence electrons , again, giving them common properties.

What Are Periodic Table Trends or Periodicity?

Organizing the table with groups and periods makes certain trends in element properties apparent. In other words, the table displays periodicity (hence its name).

There are several periodic table trends in properties, but the key ones are atomic radius, electronegativity, electron affinity, and ionization energy:

• Atomic radius is the size of an electrically neutral atom of an element. In increases moving down a group (column) because the atom gains a new electron shell. It decreases moving from left to right across a period (row) because adding protons (increasing atomic number) attracts and draws the electrons in more tightly.
• Electronegativity is a measure of how easily an atom attracts electrons that can form a chemical bond. It increases moving left to right (except for the noble gases) and mostly decreases moving down a group.
• Electron affinity is related to electronegativity. It is the energy change that occurs when a neutral atom accepts an electron. It increases moving across a period, but does not always decrease moving down a group.
• Ionization energy is the energy required to remove an electron from an atom. It increases moving across a period and decreases moving down a group.

There are other also other trends, such as ionic radius, covalent radius, and metallicity.

Who Invented the Periodic Table?

While lots of scientists have made periodic tables over the years, the one that most closely resembles the table we use today was formulated by Dmitri Mendeleev. So, Mendeleev is considered the “ inventor of the periodic table .” His 1869 table differed from the modern table in that it ordered elements by increasing atomic weight instead of atomic number. But, he made the table before protons were discovered. For the most part, using atomic weight instead of atomic number produces the same table.

Why Are the Noble Gases So Inert?

While the noble gases sometimes do participate in chemical reactions, they are mostly unreactive and are exceptions to periodic table trends. The reason is that atoms of elements of this group have stable valence electron shells . In other words, the noble gas atoms become less stable if they lose or gain electrons.

Why Are the Halogens So Reactive?

The halogens (fluorine, chlorine, iodine, etc.) are as reactive as the noble gases are stable. This group is right next to the noble gases, so why is it so reactive? The reason is that they are only one electron away from having a stable configuration. Forming chemical bonds gives the halogens this stability.

What Are the Periodic Table Groups?

While the periods of the periodic table just have numbers corresponding to their rows, the periodic table groups have both numbers and names. Probably the names arose because of the different numbering systems for the groups. The groups are the alkali metals, alkaline earth metals, transition metals, basic metals, metalloids, nonmetals, halogens, and noble gases. The lanthanide and actinide groups are actually a subset of the transition metals.
