What can you predict about an element by its position on the periodic table?
By the position of an element on the periodic table you can tell how many protons the element has in it by looking at the number above the elements symbol. You can also find the electron configuration with that same number then you can and you can you can also tell if it is f1, f2,f3...s1,s2,d1,d2...
What is the electron configuration of the neutral lithium atom?
.. [Li]+ [:I:]- (put the last 2 pairs above and below the "I" this wont let me) ..
As you move down a group elements have electron shells than those above them.?

Why do the elements S and O form a covalent bond?
If the electronegativity difference between two elements is above 1.7, then ionic bond is formed between these two. If the electronegativity difference is below 1.7, then they form covalent bond. In the case of sulphur and oxygen the electronegativity difference will be below 1.7
What is the electron configuration for lithium iodide?
The electron configuration for lithium is 1s^2 2s^1 and for iodine is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^5. In lithium iodide (LiI), lithium will lose its 2s electron to iodine, forming Li+ and I- ions. So, the final electron configuration for lithium iodide is [He] for Li+ and [Kr] for I-.
What is the electron configuration for a neutral atom of beryllium?
The electron configuration of beryllium is written as [He] 2s2. This means that it has 2s2 electrons above the configuration of Helium.
What element has an electron configuration of 1s2 2s2 2p6 3p23p3?
Phosphorus has the above electron configuration. It has 15 electrons and protons.
How is the number assigned to a family related to the electron configuration of each element in that family?
The elements on the periodic table are arranged in periods and groups. The periods run across the table horizontally from left to right, whilst the groups run vertically from top to bottom. Elements from the same group tend to have similar chemical properties since they have the same number of electrons in their outer shells. :) You can find which elements are in which groups and more about the groups themselves by looking at a periodic table for the numbers above the columns or searching Google for "group 1" for example.
Why is hydrogen (H) placed with elements in Group 1A?
Properties of Hydrogen. Hydrogen is a nonmetal and is placed above group in the Periodic Table because it has ns1 electron configuration like the alkali metals.
What is the orbital configuration of helium?
There is none because there is no noble gas above Helium
What is the same electron configuration negative ion as neon?
Sodium Magnesium Aluminium Silicon Phosphorus Sulphur Chlorine All the above seven elements have same core-electron configuration as that of neon.
Why hydrogen is placed above alkali metals and not above non metals in modern periodic table?
The electron configuration of hydrogen is similar with that of alkali metals.
Explain what a noble-gas electron configuration is?
The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point onwards. The notation is shorter to write and makes it easier to identify elements. The noble gas notation starts for elements after helium. For example, the electronic configuration of carbon is 1s2 2s2 2p2, whereas its noble gas notation is [He] 2s2 2p2.

How do the outer-shell electron configurations for ions of elements from groups 1 and 2 and 15 and 16 and 17 compare with those of the noble gases?
Elements in Group 1 have 1 more electron than the noble gas in the row above it.Elements in Group 2 have 2 more electrons than the noble gas in the row above it.Elements in Group 15 have 3 less electrons than the noble gas in the same row as it.Elements in Group 16 have 2 less electrons than the noble gas in the same row as it.Elements in Group 17 have 1 less electrons than the noble gas in the same row as it.
What does the Roman number above each column of the A group in the periodic table tell you about the electronic configuration of those elements?
Valance level
