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?
The number of valence electrons in an atom is determined by the Group number on the periodic table. For main group elements (Groups 1, 2, 13-18), the number of valence electrons is equal to the group number. Transition metals have varying numbers of 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
Which elements have to gain or lose only one electron to become stable?
Elements in Group 1 (such as lithium, sodium, potassium) have to lose one electron to become stable, while elements in Group 17 (such as fluorine, chlorine, bromine) have to gain one electron to become stable.
What does the group of the element tell you about the element?
The group of an element tells you how many valence electrons it has, which determines its chemical behavior and reactivity. Elements in the same group have similar properties because they have the same number of valence electrons.
How do you find valency of an element?
The valency of an element is determined by the number of electrons in the outermost energy level (valence shell) of its atoms. For main group elements, the valency is typically equal to the number of electrons needed to achieve a full valence shell (usually 8 electrons). Transition metals may have variable valencies based on their electron configurations. The valency can be determined by looking at the group number of the element in the periodic table.
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.
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).
What it take to become like a noble gas?
To become like a noble gas, an element must have a full outer electron shell, making it stable and unreactive. Elements achieve this by gaining or losing electrons to reach a total of 8 electrons in their outer shell, like the noble gases.
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 do you determine the number of valence electrons?
The number of valence electrons in an atom is determined by the Group number on the periodic table. For main group elements (Groups 1, 2, 13-18), the number of valence electrons is equal to the group number. Transition metals have varying numbers of valence electrons.
How do you calculate valency of an element?
The valency of an element is determined by the number of electrons an atom needs to gain or lose to achieve a full outer shell of electrons. For main group elements, valency can be determined by looking at the group number on the periodic table. Transition metals may have variable valencies.Ionic charge can also be a clue to an element's valency.
How can the number of core electrons be detemined from the periodic table?

Carbon has 4 valance elections.6 total electrons - 4 valance electrons= 2 core electrons in carbon=====================(try another element yourself to see this process )
What does the number of valence electrons tell you about a given element?
The number of valence electrons in an element determines its chemical properties, such as its reactivity and the types of bonds it can form with other elements. Elements with the same number of valence electrons tend to have similar chemical behavior.
What tends to take on electrons in order to become stable?
Nonmetals
