What is the element that borrows the electrons in a chemical reaction called?
Any element can oxidize(take an electron from) another element during chemical reactions as long as it has a partial positive charge. The most common element that is an oxidizing agent is Hydrogen.
How do you determine the number of valence electrons?
It depends on what group or family the element is in. For example, Potassium is in the first group of family so it only has 1 valence electron. However, since nitrogen is in the 15 group of family, it does not have 15 valence electrons. For double digit families, you just take the second digit, and that is the number of valence electrons. Therefore, Nitrogen would have 5 valence electrons.
How can the number of core electrons be detemined from the periodic table?
Take carbon as an example.Carbon, indicated by it's atomic number, has 6 electrons. The number at the top of carbon's group is the number of valance electrons. Carbon has 4 valance elections.6 total electrons - 4 valance electrons= 2 core electrons in carbon=====================(try another element yourself to see this process )
How can you tell whether or not an element will react with others element?
Depending on how many valence electrons in the element has, The other element could take away a valence electron to make eight
How could each what atoms react to achieve a noble gas configuration?
if the atom is an element from groups 1, 2, or 13, the atom has to give up electrons to make it have 8. For example, if you have Boron in group 13, it has 3 valence electrons, making it more likely to give up electrons than gain them. If you take 3 electrons from Boron, you get Helium. Helium is the noble-gas for Boron. B(+3) has a noble-gas configuration of He. if the atom is an element from groups 15, 16, or 17, the atom has to gain electrons to make it have 8. For example, if you have Oxygen with 6 valence electrons, it is more likely to gain electrons than lose them. If 2 electrons are added to Oxygen the noble-gas configuration becomes Neon. O(-2) has a noble-gas configuration of Ne. if the atom is an element in group 14, it can either gain or lose electrons. so the noble gas configuration could be the 4 electrons less or 4 electrons more than it. For example, if you add 4 electrons to Carbon you get Neon but if you take away 4 electrons you get Helium.
How do you find valency of an element?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
What does the group of the element tell you about the element?
Just a disclaimer, I haven't studied this in a little while, so some information be a tad inaccurate, but that is what Google is for. A group of elements goes in columns along the periodic table. Besides groups having specific names, all elements in the same group have the same number of valence electrons, which are the electrons on the outermost 'ring' around the nucleus. For example, take the element Sodium, which has 11 total electrons. The first ring carries 2 electrons, and the rings from then on carry 8. So, 2+8=10, leaving 1 (11-10) electrons on the outermost shell. There is your number of valence electrons. Naturally, elements want a complete electron shell, which means a full set of 8 electrons. This plays into the ways element groups react with others. Group 1, the alkali metals, react well with group 17, the halogens.

An element from group eighteen from the periodic table is?
An element from group eighteen from the periodic table is commonly referred to as a "noble" or "inert" gas. These elements have filled electron shells, and therefore they do not share, take or give away any electrons. As a group they do not react with othere elements to form compounds (with only a couple of rare exceptions).

Does group 1 give or take valance electrons?
give
What happens when you had a proton to the nucleus of an atom?
Im thinking you mean add instead of had? well when you add a proton it becomes a different element because each element has a different number of protons. When you add electrons or take away electrons they become ions. If the neutrons in the nucleus changes it becomes an isotope. To conclude, each element has its own unique proton count.
How can the number of core electrons be detemined from the periodic table?

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.

What tends to take on electrons in order to become stable?
