Wonderful overall as it allows me to type instead of hand write certain forms. I am hoping that it will be easier to use to line all cells up so it looks more neat.

My only two complaints are the price and the fact that if you only want one page out of a file with a lot of pages... it seems the only way to "quickly" do it is to go in and individually delete each unwanted page. Otherwise, it does most of what I want.

this program has made my life so much easier - I use it to fill in PDF forms for my doctor visits as well as for business - keeps everything simple and in one place. Very user friendly.

Tree saver
My son has to do virtual school with everything going on at the moment. This is great for filling out worksheets instead of printing and killing trees

The product works
I was able to fill forms and use powerful tools. They are not Adobe though and they charge nearly as much.
The web sight interface was easy to use.
They charge WANton much especially if you want the option to use it for only a short period of time.

I find PDFFILLER to be a very a helpful and resourceful tool for all my business tax filling and contractual needs… thank you very much for this dependable tool

Easy to use and having documents saved in different versions on the cloud was very helpful. Kind of expensive for the level of support that I needed.
2021-05-18
Combining two files was relatively easy once I read the How to Guide three times to figure it out. But editing text in the file resulted in a change in the font that was not particularly satisfying and could not be corrected.

For s-block elements, group number is equal to the number of valence electrons. For p-block elements, group number is equal to 10+number of electrons in the Valence shell. For d-block elements group number is equal to the number of electrons in a (n-1) d subshell + the number of elect.
How do you find the group number and period number of an element in class 10?
Valence Electron — Group 1. Valence Electrons — Group 2. To 8 valence electrons — Add 10 to the valence electrons to get the group number of the element.
What is group number in periodic table?
Group (periodic table) A group is any column on the periodic table. Elements in the same group usually have similar properties, because they have the same number of electrons in the outermost electron shell. There are eight main groups of elements, numbered 1, 2, and 13-18.
How do you find the group and period of an element?
The period of an element corresponds to the principal quantum number of the Valence shell. The block of an element corresponds to the type of orbital which receive the last electron. For s-block elements, group number is equal to the number of valence electrons.
How do you find the group and period of an element in class 10?
Valence Electron — Group 1. Valence Electrons — Group 2. To 8 valence electrons — Add 10 to the valence electrons to get the group number of the element.
What group number is S in?
The s-block is on the left side of the conventional periodic table and is composed of elements from the first two columns, the nonmetals hydrogen and helium and the alkali metals (in group 1) and alkaline earth metals (group 2).
