Would a magnesium atom prefer to lose or gain electrons?
Magnesium is in the second group (column) of the periodic table, so it has two valence electrons or electrons in its outer shell. so in order for it to fulfill the octet rule (get eight electrons in its valence shell most of the time), then it would rather lose two electrons and have a full valence shell than gain six electrons.
How many valence electrons are there in one ozone molecule?
six, read your periodic table and look at the electron configurations. the last number is how many electrons are in the valence orbital. the number of electrons in that valence orbital and how many valence electrons there are in that atom. oxygen has a 2-6 configuration, hence six valence electrons. lewis dot diagram has a capital O surrounded by three pairs of dots (six total), chemistry is easy and fun for everyone.Oxygen has 6 valence electrons.
What indicates the valence electrons on the periodic table?
Valence numbers, in relation to the periodic table, mean electrons. If you know the basics of chemistry, you know that electrons form pairs in the "shells" of an atom. The valence number refers to the number of electrons in the outermost "shell".
How do you find valency of any element?
The valence is the outer most shell and im assuming you need the amount of electrons on the outer most shell which would be the valence electrons. There can be no more than 8. The rule is 2-8-8. It could be done by referring to the group of that element in the periodic table.
How many valence electrons does a sulfur atom have?
Both have six valance electrons. That is what the number at the top of their column means.
Compare the number of valence electrons on oxygen atom has with number of valence electrons a selenium atom has Are oxygen and selenium in the same period or group?
They both have 6 valence electrons. Oxygen and Selenium are in the same group.
How can you determined the number of valance electrons by looking at the periodic table?
Elements are located on the periodic table based off of their atomic number, but the vertical columns they are in (groups) show how many valence electrons they have. If an element were in Group 3 of the periodic table, it would have 3 valence electrons, and so on. This doesn't apply to the Transition Metals, so one should skip straight to Group 14, where the elements all have 4 valence electrons. Group 15 has 5, Group 16, 6, etc. The one exception to this is Helium, which is in Group 18 but only has 2.
How many valence electrons would be found in an atom of potassium?
Potassium is in group 1 of the periodic table, so the answer is 1 electron.
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"
When is it necessary to start a new period in the periodic table?
Periods in the periodic table represent the number of electron shells necessary to fit all of the electrons. Once you fill the valence shell of an atom, the next electron must go in a new electron shell. This would constitute a new period on the periodic table.
Would a magnesium atom prefer to lose or gain electrons?

How many valence electron's does sulfur have?
Sulfur has sixteen electrons total, two in the inner shell, eight in the middle, and six in the outer. This means that it would have six valence electrons.
How many valence electrons are there in one ozone molecule?
six, read your periodic table and look at the electron configurations. the last number is how many electrons are in the valence orbital. the number of electrons in that valence orbital and how many valence electrons there are in that atom. oxygen has a 2-6 configuration, hence six valence electrons. lewis dot diagram has a capital O surrounded by three pairs of dots (six total), chemistry is easy and fun for everyone.Oxygen has 6 valence electrons.
Two elements are found in the same column of the periodic table You would expect these elements to have?
same number of valence electrons, so are their chemical properties more or less the same.
How do you calculate formal charge?
to calculate the formal charge:Take the number of valence electron the neutral atom would have (found on the periodic table) and subtract it from the number of electrons in lone pairs +1/2 of the number of electrons in bonds
