What can you infer about the number of electrons in the outermost electron cloud of a silicon atom based on silicons position on the periodic table?

Silicon is in Group 14, and all members of Group 14 have 4 electrons in the outermost energy level, or valence shell (14-10). Also, silicon is in the second column of the p-block on the Periodic Table. All members of the p-block have a valence shell of ns2np1-6, where n is the outermost, or highest energy level. Since silicon is in the second column of the p-block, and it is in period 3, its electron configuration is [Ne]3s23p2, in which the outermost, or highest energy level, or valence shell is the 3rd energy level, which contains 4 electrons.

How does the structure of the atom change as its position on the periodic table changes in reference to their respective groups and periods?
The number of protons and electrons is specific for atoms in a neutral state.
How is each element placed in the periodic table?
Elements are arranged into rows in order of increasing mass, so that elements with similar properties were in the same column. They are organized by type, such as nonmetals, metals, and metalloids, and solids, liquid, gas, or not found in nature.
Why is the ion charge of iodine -1?
Iodine is a halogen (group 7 of the periodic table), and halogens are supposed to have seven valenced electrons to match the amount of protons in their nucleus. However, in order to form a full octet of valence electrons, iodine atoms are willing to accept one more electron. This electron brings iodine's charge down to -1. And unlike other halogens that are smaller than iodine (fluorine, chlorine, and bromine), iodine is large enough so that its negative charge can be distributed more evenly. This makes iodine stable with a negative charge, and a good leaving group in chemical reactions (something you will probably learn later on in organic chemistry).
Explain how does the sea of electrons model of metallic bonding explain the shared characteristics of metals?
Basically, electricity is a force caused by electrons hitting each other. The electron sea model explains the conductivity of transition metals by showing that they hang onto their many electrons loosely and are practically floating in them. With so many free electrons, it's a lot easier to conduct electricity.
What information can you gather knowing the atomic number and mass of an element?
If you know the atomic no. and atomic mass, then the no. of electrons, no. of protons and no. of neutrons can also be determined. Atomic No.=No. of electrons = No. of protons. No. of neutrons=Atomic mass-Atomic no. Also, by no. of electrons you can determine its valency and the no. of valence electrons.
What relationship is there between the outermost suborbital in an atom and its position in the periodic table?
The position in the periodic table can range in size moving from left to right, and it has a wider range of numbers, but in the outermost suborbital, it can only range from 1-8 valence electrons!
How does the number of electrons in outer energy levels relate to the position of an element in the periodic table?
the group number shows the number of electrons in the outermost energy levels. forexample sodium (Na) have 1 electron in the outermost shell and is placed in the group 1. Elements are grouped in rows depending on their energy levels, or valence electron numbers. Columns of elements are those that are chemically similar, or react
Elements have their position on the periodic table because?
atomic no. or basically according to the no. of electrons in their outermost shell whcih reflect the property of individual atom
What compares alkali metals halogens and noble gases with respect to position in the periodic table the ability to react with other metals yes or non the number of electrons in the outer orbit?
Alkali metals are positioned to the far left in the periodic table. They react with hydrogen and oxygen(no they don't react with metals) and they have one electron in the outermost orbit.Halogens are positioned next to the noble gases in the periodic table. They react with nonmetals (no they don't react with metals) and they have seven electrons in the outermost orbit.Noble gases are positioned to the far to the right or last column in the periodic table. They never react with metals (no they don't react with metals) and they have 0 electron in the outermost orbit because they are very unreactive, which mean they are neutral (0/canceled).***Bold Words Important Keys for the Words***(Answers are found in page #110, 111, and 112 in the Grade 9 Nelson Science Textbook for Ontario, and also use the modern periodic table as your guide.)
How does the number of electrons in the outer energy levels relate to the position of an element in the periodic table?
Electrons in the outer most energy level is called "valence electrons." Groups are the columns of the periodic table. The more valence electrons (up to 8), the closer to the right. The number of electrons needed to make an atom stable is 8. (Minus Hydrogen and Helium, which only need 2 electrons to be stable.)
What does the electron configuration tell you about an element?
i think it tells about the stability of that element.add The position and number of electrons on an element determine its chemical properties. Generally, the outermost shell of electrons.But in the rare earths, the outermost shell of all of them, contains a similar number of electrons, and it is the inner shells that vary in their number. Hence their similar but subtly different properties.
Carbon position in modern periodic table?
it is in group, 4 and in period 2 group means how many electrons in outer shell, and period means how many electron shells it has:)
What property determines an elements position on the periodic table?
Position of Periodic Table describes chemical properties. it is estimated from its position in table.
What controls an element position on the periodic table?
The group number is found by the number of valence electrons. The period number is found by the number of energy levels. These 2 controls the position of an element.
The electron cloud model describes the of electrons in an atom?
The model is applied to movement and position of electrons in the atom.
How many valence electrons are there for calcium?
2, as indicated by its position in periodic column 2.
What can you predict an element from it's position in the periodic table?
how many electrons it has---how many valence electrons and how many levels of electrons. its Atomic Mass its atomic number
