The electrons on the outermost shell of an atom tell you how many valence electrons an atom on the Periodic Table has , and this number can be used to apply to the octect rule .
What else can I help you with?
If an atom has a stable number of electrons how can you tell?
If an atom has a stable number of electrons, it will have a full outer electron shell (valence shell). This full outer shell will typically have 2, 8, 18, or 32 electrons, depending on the period the atom is in. Atoms with full valence shells are considered stable because they are less likely to undergo chemical reactions to gain or lose electrons.
What information do the periods number give you?
The periods in the periodic table tell you the energy level where the last electrons are being added. So, in period 1, the outermost electrons are in the first energy level or shell. In the 3rd period, the outermost electrons reside the the 3rd energy level, and so on.
How is oxide ion formed?
Oxide ions are formed when an oxygen atom gains two electrons to achieve a full outer electron shell. This results in a stable oxide ion with a 2- charge. Oxide ions are commonly found in compounds like metal oxides and are an important component in many chemical reactions.
What does the group number of the periodic table tell you about the structure of an atom?
The group number of an atom in the periodic table tells you the number of valence electrons that atom has. Valence electrons are involved in the atom's chemical reactions and determine its chemical properties. Atoms in the same group have similar chemical behaviors due to having the same number of valence electrons.
The atomic number of an atom indicates the number of?
The atomic number is the number of protons in the atom. In the case of a neutral atom (as opposed to an ion), the atomic number is also equal to the total number of electrons.
If an atom has a stable number of electrons how can you tell?
If an atom has a stable number of electrons, it will have a full outer electron shell (valence shell). This full outer shell will typically have 2, 8, 18, or 32 electrons, depending on the period the atom is in. Atoms with full valence shells are considered stable because they are less likely to undergo chemical reactions to gain or lose electrons.
What columns in periodic table tell us about the atom?
How many valence (outer shell) electrons an element has.
Property you cant determine about an atom from the atomic chart is?
Group numbers tell us that how many electrons an atom contain in its outer shell. Eg. Na11 have 1 electron in its outer shell it means Na belongs to group 1. and so on.
How can you tell from the periodic table how many outer shell electrons an atom will have?
you cant its inposible just pay attention in class and u will find out.
How can you tell if an atom has the same valence as carbon?
You can tell if an atom has the same valence as carbon by looking at its outermost electron configuration. Carbon has 4 valence electrons, so any atom with 4 electrons in its outer shell, like silicon, would have the same valence as carbon.
How can you tell if an atom has a negative charge?
you can tell an atom has a negative charge if its outer shell is not stable(happy)/full
What does the number of dot tell us about each atom?
Lewis dots are concerned with electrons in the outer most shell of an atom. This means that no matter how many electrons an element contains, Lewis dots will never number higher than eight.
How many electrons will a non metal generally have in its outer shell?
non-metals have between 3 and 8 electrons in the outer shell. You can tell how many they have by looking at which period they're in on the periodic table, period 13 elements have 3, period 15 elements have 5 ect.
How can you tell if an atom is chemically reactive or not?
Chemically reactive atoms typically have one or more outer shell electrons that are not tightly bound. Atoms with a full outer shell are usually stable and less likely to react with other atoms. The reactivity of an atom can also be influenced by its position in the periodic table and its electronegativity.
How can you tell that the beryllium atom is unstable?
You can tell that the beryllium atom is unstable because beryllium only has 2 valence electrons in its outer shell. An atom becomes stable when it has eight valence electrons, so in the case of beryllium it would have to lose those 2 electrons in its outer shell to become stable. often forming a cation with a 2+ charge.
How do you tell how many electrons are in the outer layer of an element?
The outermost principal shell -or regions around the nucleus where electrons move- contains the valence electrons. The number of valance electrons can be calculated for the columns with A's above them. The number given to the column represents the number of valence electrons (written before and next to the A). For instance, Lithium (Li) and Sodium (Na) have one valence electron because they are in column one. During chemical bonding, these two elements and others in their column have the same configuration of outer electrons; thus, they tend to lose their single electron in order to gain a full outer shell. Similarly, oxygen (O) and sulfur (S) have 6 valence electrons, so they tend to gain electrons to make their full outer shell.
What does an elements location on the periodic table of elements tell you about that element?
The amount of electrons and their position in the atom is the main thing. The atomic number of an element is it's amount of protons. That makes the periods (rows). Groups are put in place using where the electrons are in the atom (how many electrons are in the outer shell of that atom). All elements in a representative element group have the same amount of electron sin the outer shell. (e.g. all elements in Group 1 have 1 electron in the outer shell)
