The trends are that when you move from left to right the number increases. As you go from right to left the number decreases. If you continue to figure this out from the Periodic Table, you will be able to find the electronegativity of the elements of the periodic table.

∙ 12y agoGoing from the left to right, top to bottom, the atomic number increases, which indicates the number of protons in an atom. E.g. Hydrogen is made up of one proton and one electron, therefore its atomic number is one. Helium has two protons and two neutrons, therefore it is number two.

Which element has the largest size of atoms?
Atomic radii have not been measured or calculated based on theoretical principles for all of the elements. However, based on the information available in the wikipedia tables of atomic radii it would appear that the largest atom will prove to be that of francium.
What are periodic trends?
periodic trends are the tendencies of certain elemental characteristics to increase or decrease as one progresses along a row or column of the periodic table of elements.
What is the periodic trend for atomic size from top to bottom in a group?
The size of an atom refers to its atomic radius. Atomic radius generally increases down a group. This is because the number of energy levels increase down a group with each additional period. Each of the subsequent energy levels are larger than the last, increasing the distance of the electrons from the nucleus, which increases the atomic radius.Atomic radius generally decreases across a period. This is because electrons are being added to the same energy level at the same time that protons are being added to the nucleus. This creates a stronger force of attraction by the nucleus for the electrons, which pulls the electrons closer to the nucleus, decreasing the atomic radius.It is important to note that the periodic trends are not laws. There are exceptions to the general trends in both the representative elements and the transitional elements.
What is true about elements with low electronegativity?
The atomic size for the element is very large.
What are names of the trends in the periodic chart?
Atomic size decreases from left to right in a period hence ioniztion energy increases from left to right.But atomic size increases from top to bottom in a group hence ionization energy decreases from top to bottom.
What trends in size are found among elements in the same period?
The atomic radius decrease from left to right.
Does sodium have the smallest atomic size?
no, hydrogen has the smallest size among all elements
When the three elements se te and br ara arranged in order of increasing atomic radius?
Arranging Se, Te, and Br in order of increasing atomic size, you get: Br --> Se --> Te The trends are: atomic size increases right to left, and top to bottom.

How do you tell the size of an elements atomic radius?
The atomic radius of chemical elements is expressed in picometers (pm).
Which element has the largest size of atoms?

What are 2 reasons for studying the periodic table?
Periodic table of elements provides us a lot of information about element's intrinsic properties. We can get the atomic weight of an element by looking at the periodic table. Trends about the electronegativity and atomic size can also be computed.
What happens to the atomic size of the elements as on goes from the top to the bottom of a group?
Atomic size decreases as one moves from bottom to top in a group. The elements get smaller because they have less stuff in them.
What are periodic trends?
periodic trends are the tendencies of certain elemental characteristics to increase or decrease as one progresses along a row or column of the periodic table of elements.
Why do both and atomic size and ionic size increase as you move down a group?
Both trends hold for both positive and negative ions.

What neutral atoms has the largest atomic size between Li Fl Cl and Mg?
From the given elements, Mg has the largest atomic radius, hence the size.
