What do valance electrons tell us about atoms?
Valence electrons are the outermost electrons in an atom's electron cloud, and they determine the atom's chemical properties. The number of valence electrons influences how likely an atom is to form chemical bonds with other atoms. Elements with the same number of valence electrons tend to exhibit similar chemical behavior.
Is covalent gained lost or shared electrons?
Depends on the atom, remember that metals want to loose all valence electrons and non-metals want to gain electrons so that it has 8 valence electrons (similar to noble gases) For example Al (Aluminum) is in group 3, it's a metal so it will lose 3 valence electrons making it have a charge of +3 or AL3+. Another example, F (Florine) has 7 valence electrons, it's a non-metal so it will gain 1 to become stable, making it have a charge of -1 or F1-. Hope this helps Ya! :-P
What does the number of valence electrons tell you about a given element?
If its positive it tells u that it has that number of valence electrons. If negative it tells you that it requires that number of electrons to make the valence electrons filled up/stable. If you know which Ion it is, you know the number of valence electrons of the neutral Atom. It corresponds to the group in the periodic table, the element is in. For example: Mg. It's in group 2, so it has 2 valence electrons. The oxidation number now tells you how many more or less electrons the atom has. For example: Mg(II) has 2 positive charges, hence two electrons less. That means it has 0 valence electrons. Take complete number of valence electrons, subtract the oxidation number and you get the number of valence electrons in the ion.
Which part of the periodic table square tells you the number of protons and electrons?
The atomic number, which is located at the top of each element square in the periodic table, tells you the number of protons and electrons in an atom of that element.
What does electron configuration tell you about an element?
Electron configuration tells you how electrons are arranged in an atom's energy levels. It provides information on the number of electrons in each energy level and helps predict an element's chemical properties and reactivity. By understanding electron configuration, you can determine an element's potential to form bonds with other elements.
What does the valence pattern represent?
The valence pattern represents the number of electrons that an atom needs to gain, lose, or share in order to achieve a stable electron configuration. It helps determine the type of chemical bonds an atom can form with other atoms.

The number of valence electrons influences how likely an atom is to form chemical bonds with other atoms. Elements with the same number of valence electrons tend to exhibit similar chemical behavior.
What does the period tell you about electrons?
The period tells you how many energy levels an atom has.
Are periods valence electrons or electron shell?
The period tells you the valence ELECTRON SHELL (energy level). The group tells you the number of valence electrons.
What tells you how many protons and electrons an element has?
The atomic number = Number of protons = Number of electrons
Is it true that elements with a high electronegativity value tend to form positive ions?
The electronegativity value tells you how much that element "wants" an electron, therefore, an element with a high electronegitivity value would generally give a negative ion. The definition of a negative ion is an atom with more electrons than protons.

Another example, F (Florine) has 7 valence electrons, it's a non-metal so it will gain 1 to become stable, making it have a charge of -1 or F1-. Hope this helps Ya! :-P
Why do elements tend to form compounds?
it tells how many atoms are in the unit to be stable
What does the atomic number tell you about the element?
it tells you the number of protons and electrons
What does the number tell you?
the periodic number tells you the number of electrons and protons.
What does an atomic number tells you?
The atomic number tells you the number of protons in the nucleus. As such, it defines the element, since each element has a definite and defined number of protons. In the element, it also tells you the number of electrons, since the element (not the ion) has a neutral charge and protons = electrons.
What does the number of valence electrons tell you about a given element?
If its positive it tells u that it has that number of valence electrons. If negative it tells you that it requires that number of electrons to make the valence electrons filled up/stable.
