What is the electron dot structures of elements?
The Lewis structure for an element is the element symbol surrounded by dots numbering the total amount of valance electrons. Imagine a box is around the symbol...place the dots one on each side of the box. once there is one dot on each side, you will have to start putting a second one on each side. since no element has more than 8 valence electrons, you will never have more than 2 dots on each side Ex: hydrogen has 1 valance electron, so its Lewis dot structure will be... . H Note that is does not matter which side the dot is on
How many valance electrons are found in a atom of each what elements Helium?
Helium has two valence electrons
How many valance electrons are found in an atom of each what elements Neon?
there are 8 electrons in the valence shell of neon
Explain why the transition metals are sometimes referred to as the d-blok elements?
the transition metals constitute groups 3 through 12 and are sometimes called d-block elements because of their position in the periodic table; while they all have the same valance electron orbital 'd'.
What is the theory of bonding in pure metals?
Pure metals form a metallic bond, in which each atom contributes its valance electron or electrons as the case may be, to the common electron cloud shared by all the atoms of that particular piece of metal.

What is the valence electron configuration of each element in group 1?
All elements in group 1 have 1 valence electron.
How do the valence electrons configurations of the alkali metals compare with each other?
The valance electron configuration is the same in each at ns1 where n = the period number.
How do the valence electron configurations of the alkali metals compare with others?
The valance electron configuration is the same in each at ns1 where n = the period number.
How do you find the electron dot configuration?
to find the electron dot configuration of an element simply draw dots, symbolizing valance electrons, in a way that they are farthest from each other around the symbol of the element you are using.
Is each dots in an electron dot diagram used to represent valance electrons?
Yes, the dots in an electron dot diagram represent valence electrons.
How many valance electrons are found in a atom of each what elements Helium?
Helium has two valence electrons
How do elements change from left to right across a period of the periodic?
The elements of the Periodic Table increase in atomic number as you move across and down. This indicates more protons, and a larger atomic nucleus. The number of electron shells increases as well, with elements with filled valence shells at the right (noble gases). Also, generally elements become less reactive as it moves from the left to the right.As elements go from left to right across the periodic table, each element has one more proton and one more electron than the element to its immediate left. This affects valance (or outer shell) electrons. The column on the extreme left has just one valance electron, then the next column has two, the next has three. There isn't a smooth, uninterrupted progression from one valance electron to eight, on the far right, because the transition state elements, which are all metals, intrude into the sequence (this happens because some atoms have incomplete inner electron shells, rather than filling each shell before starting the next shell). But aside from that complication, elements go from metals on the left to nonmetals on the right, ending up with the noble gas elements on the extreme right.

What is the name of the group of elements with two valence electron in each period?
The name of the group of elements with two valence electron in each atom is "alkaline earth metals."
What happens in the combination of sodium and chlorine to yield table salt?
A sodium atom has one valance electron which it donates to a chlorine atom which has seven valance electrons; as a result of this electron exchange, both the sodium and the chlorine will then have complete outer electron shells, and they also will both become electrically charged ions which will attract each other.
