How can you use a periodic table to predict the number of valence electrons an element has without having to draw the Bohr diagram?

In general, except for the transition elements, the group number will tell you the number of valence electrons. For example, Na is in group 1 and has 1 valence electron. Cl is in group 7 and has 7 valence electrons.

Periodic table
What predicts an element's properties?
The answer you are probably looking for is the periodic table, which arranges the elements. The periodic table can help predict properties of an element based on the element's location. All the elements in a veritcle collum (also known as family or group) will have the same number of valence electrons and thus behave in a similar manner. Elements can also be compared to one another on the horizontal axis(the period). i.e. moving from left to right elements become less metalic and do not exibit metallic properties as stongly. General location on the table can tell you what type of element it is; metal, nonmetal, metalloid/semimetal. or the # of protons and electrons in the element, the atomic mass.
Using the periodic table predict how many outer level electrons will be in elements 114 116 and 118?

What can you predict about an element from its position in the period table?
how many electrons it has---how many valence electrons and how many levels of electrons. its atomic mass its atomic number
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 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
Can the periodic table predict the number of isotopes of elements?
No. The position of an element in the periodic table cannot predict the number of isotopes it has. However, the position of an element in the periodic table can predict other properties like the charge of its ion, the formula of its oxide, the acidic or basic nature of its oxide, etc.
What element on the periodic table would you predict to that the least attraction for its outer level electrons?
I think the elements with more number of shells and least number of electrons in the outer most shell would be the one. For example francium.
What can you predict about an element from its position in the periodic?
You can see if its a metalliod or a metal or a non-metal.

Periodic table
When trying to predict the location and motion of electrons in atoms scientists must work with?
They use a Periodic Table.
Use periodic in a sentence?
Some stocks have periodic rises and falls. The periodic table lists every element know on Earth. Periodic events are easy to predict.
What can you use the Periodic Table of Elements for to predict about the elements?
An element's physical and chemical properties. You can also predict what elements will bond with each other.
What are valence electrons and what do they determine?
They determine many things. They can be used to predice hybridization, determine octet, be used to assign formal charges. The simplest answer would be for a intro to chem class, they determine the number of electrons in the atom's "outer ring"
What is the importance of valence electrons in the organization of the periodic table?
The importance of valence electrons is that atoms in the same group ("groups" in the periodic table are the vertical columns- for example, nickel and platinum are in the tenth column; therefore, in the same group). Atoms of elements in the same group have the same number of valence electrons, so they have similar properties. Hope that helped with your homework! ;D

How can the periodic table be used to predict the properties of an element that has not been discovered?
It can't. the properties of an element determine it's group placement, without knowledge of these properties (or, indeed, the element itself) it would be impossible to place an element in it's proper place on the periodic table.
