How can the periodic table be used to predict how many electrons a certain metal atoms loses to form an ionic compound?
SoccerB
The most common way to determine the ion of an atom on the Periodic Table is to look at the group it is in. Moving from left to right the elements will usually have the ionic charges of +1,+2,+3,+-4,-3,-2,-1. All elements in each group will have the same ionic charge . The transition metals are not as easy as this but a general method to use is that most transition metals have a charge of +2. This iosnt true for all of them but if you are not sure on their charge it is bsest to go with +2. Otherwise the other method i have said is a good way to determine the ion that will form

∙ 13y agoIf the periodic table used is the usual "long form" table with 18 columns numbered from left to right and the symbol of the metal of interest is in column 1 or 2, the atom will lose the same number of electrons as its column number to form its most stable cation. The largest number of electrons that the atom might lose to form a cation is usually the same as the column number for columns 3 through 7, but in practice, almost no cations with charges greater than +4 are stable. However, the metals in these columns often share the maximum number of electrons predicted by this rule to form anions with very electronegative non metals such as oxygen and fluorine. Metals in columns 13 through 15 can usually lose no more than the number corresponding to the last digit only of the column number to form cations, but again + 5 cations are rare. (Note that the atoms in columns 14 and 15 in the third period or lower are usually not metals at all.)

How do you predict if a covalent compound will be polar or nonpolar based on the elements' positions on the periodic table?
Yes

Can a conjution be in the middle of a compound predict?
yes a conjuntion can be in the middle of a compound pretict!
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.
Which scientific method could be used to predict the properties of an element?
Periodic table
When trying to predict the location and motion of electrons in atoms scientists must work with?
They use a Periodic Table.
How do you predict if a covalent compound will be polar or nonpolar based on the elements' positions on the periodic table?
Yes
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 can you predict from an elements place in th periodic table?
its valence electrons, its number of energy levels, how reactive it is, and some properties it has

What does a periodic table predict?
A periodic table can predict elements that are not yet confirmed or identified.
What does the study of the periodic table have to do with classification and prediction?
The elements in the Periodic Table are arranged so that elements in the same group (column) will exhibit certain similar characteristics with others in that same group, but different periods (rows). So you can predict, with a certain degree of confidence, how a certain element may behave by where it is located on the periodic table, based on what you know about how other elements in the same group behave. This is mainly due to the valence electrons (the outermost electrons) being the same configuration as others in the same group. The valence electrons are a big determining factor as how that element will react with other elements. They do not all behave exactly the same, but similar.
Was Mendeleev's periodic table accurate enough that he was able to use it to predict the existence and several properties of certain elements that had not yet been discovered?
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.
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 use on the periodic table of elements to tell you about a certain chemical?
We can predict the electron configuration, some chemical and physical properties, the atomic weight, etc.
