Sodium has one valence electron. As you move left to right on the Periodic Table in the columns, the amount of valence electrons increases. It may get a little trickier for transition metals, but that is a separate question.
What else can I help you with?
Why do sodium and potassium have the same number of dots in their electron dot diagrams what does this tell you about the chemistry of these two elements?
No,sodium has an atomic number of 11 therefore it has 11 electrons with the electronic configuration 2,8,1whereas potassium has 19 electrons with an electronic configuration of 2,8,8,1They both have different numbers of electrons but have the same number of electrons in their 'valence' shell ( outer most shell) as they are both in Group 1
If one chlorine atom is in the presence of one lithium atom and one sodium atom which one will it bond with?
It will bond with sodium to create NaCl, salt. This is because it has more attractive force. Take a look at an activity series that will tell you which elements will form a compound over another element in a chemical reaction. See the link below.
Does milk contain sodium?
Milk does contain sodium. How much I couldn't tell you, it probably depends on the type of milk.
Why is sodium chloride not considered a molecular compound?
Look at the electronrgativity difference between sodium and chlorine. It is very high and that means the chlorine can take an electron from the sodium making charged particles called ions. How can you tell quickly?? Dissolve salt in water and test the solution for conductivity. It conducts very well. The particles must be charged, so sodium chloride must be ionic, not molecular.
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.
How can you tell potassium is in group one from its atomic structure?
you can tell an atom's position in the peiriodic table by its valence electrons in the outermost shell. potassium therefore has one free valence e-, placing it in group 1 depending on how many shells the atom has determines which rows (horizontal) it is in
Why do sodium and potassium have the same number of dots in their electron dot diagrams what does this tell you about the chemistry of these two elements?

What does the group tell us about the structure of the atom?
The group or family of an element in the periodic table tells us about the number of valence electrons an atom of that element has. This can provide information about the atom's reactivity and chemical properties. Different groups have similar characteristics due to their similar outer electron configurations.
How can you tell using the periodic table that sodium and potassium are similar?
You can tell by the location, and the fact that they are both in the same column. Elements in the same column (or group) have similar properties.
How many electrons are in the outer energy level of group 7 a elements?
To start off, the electrons on the outermost energy level of an atom are called valence electrons. You can tell how many valence electrons an energy level has by finding out its group number. If an element is in group one, than it has one valence electron.
What does the periodic table tell you about the properties of two elements in the same group?
Two elements in the same group have same characteristic properties.They behave in similar way when exposed.For example : lithium and sodium which belongs to group one.
Is sodium metal or nonmetal tell you?
Sodium is an alkali metal.
What can you tell about the element sodium by looking at the periodic table?
1. Sodium is in the first group of the periodic table and in the period 3; it is an alkali metal. 2. Sodium is a solid metal, forming monovalent cations. 3. Sodium is very chemically reactive. 4. The atomic weight of sodium is not great. 5. The density of sodium is not great. 6. The chemical symbol of sodium is Na. 7. Sodium hydroxide is a strong and corrosive base.
What does being in Group 1 in the periodic table tell us about these elements?
These elements all want to lose 1 electron to have a noble gas electron configuration and are thus extremely reactive, particularly with water.See the Related Questions to the left for more information about the Group 1 alkali metal elements.
What type of ions do the elements of group 1 form?
Elements in group 1, also known as the alkali metals, typically form ions with a +1 charge by losing one electron. This is because they have one electron in their outermost energy level, making it easier for them to lose that electron to achieve a stable electronic configuration.
How is the periodic table used to describe atomic structure?
The periodic table can be used to describe atomic structure by using the period to tell you how many shells (principle quantum number) there are in an element, and the group number can be used to tell you the number of valence electrons in the outermost shell.
