8
Based on their placement on the periodic table what about ion formation is correct There is more than one correct statement?
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
Which element in group 17 is least likely to loose an electron?
(F) Flourine
What is a dot and cross diagram and how is it created?
i need to know this information and much more information for school. and i wish you can help me on it. what does a dot diagram show? what are two things a dot diagram must show? how can the group number help in determining the number of valence electrons? what is true for the dot diagram for every element in a group? what is helium's dot diagram? why is helium's dot diagram different? what do electron configurations show? how is the total number of electrons for an aton determined? what do all the number in the electron configuration equal to? why is knowing the period an element is in necessary to write a correct electron configuration? what does the group number tell us about the electron configuration? what are the electron configurations of Lithium (Li), Carbon (C), Magnesium (Mg), Silicon (Si), Chlorine (Cl), Potassium (K)?
What group has the electron configuration 1s2 2s2 2p6 3s2 3p3?
That is the element phosphorous
If an element has 1 valence electron what group is it in?
That element would be in the Alkali Metals (group one)
What are the Every element in group one has one electron in its outer shell Every element in group two has two electrons in its outer shell?
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
An element that has the electron configuration Ne3s23p5 is in which period?
It is in group 17.
How many valence electron does a group 18 element have?
8
What is the period block and group of the element with the electron configuration Ar 3d74s2?
the element belongs to 4th period, 9th group, it is a d block element. the element is cobalt
What element has 2 electron shells and 4 valence electrons?
Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.
What does each dots in an electron dot diagram represent?
The dots are the valence electrons in the outermost shell of an element. The number of valence electrons are the group number of the element (H=1, O=6, C=4 etc.)
How many dots would be shown on the electron dot diagram for the element silicon?
It depends which element it is. Hydrogen would have one while carbon would have 4 dots. Refer to http://upload.wikimedia.org/wikipedia/commons/thumb/0/02/Electron_dot.svg/300px-Electron_dot.svg.png for additional information.

A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
What is the element in the first group that are reactive highly and has on electron shell?
metals
Which element group have the most negative electron affinities?
Fluorine flourine is the most electronegative element
WHAT Sulfur is element 16. How many dots would you have to show in the electron dot diagram for sulfur a. two c. eight b. six d. sixteen?
Sulfur is in group XVI (or 6A) and so has 6 valence electrons. The electron dot diagram for S would thus have to show (b) six dots.
