What else can I help you with?
What are two elements with one electron in their outer shells?
Any two of the alkali metals, group I of the periodic table: Li, Na, K, Rb, Cs and one extra: the only non metal in group I Hydrogen (H2).
What three elements have the most similar physical and chemical properties?
Magnesium, strontium , and barium belong to group 2A of the periodic table. These have two valence electrons in their outermost shell. So these three elements have similar chemical properties. But the other given elements do not lie in same group so they have different chemical properties.
How many elements are in group 1 on the periodic table?
These six elements are Li, Na, K, Rb, Cs and Fr.
Define group as it relates to the periodic table?
A group is a vertical column on the periodic table. The elements in a group have very similar chemical properties because their outer electron configuration is the same. Ex: the first column on the left, Li, Na, K etc. Each of these has one outer electron, causing each to react in very similar ways. They lose that electron and form a positive ion.
Give the letters of two elements in the same period?
Sodium (Na) and Magnesium (Mg) are two elements in the same period (period 3).
What two elements that belong to the same group?
Two elements that belong to the same group are sodium (Na) and potassium (K), which both belong to Group 1 (also known as the alkali metals) on the periodic table.
Do the element Na and K belong to the same period or the same group?
Sodium (Na) and potassium (K) belong to the same group on the periodic table, Group 1, which is the alkali metal group. They have similar properties due to being in the same group, but are located in different periods - Na is in period 3 and K is in period 4.
What element does Na resemble?
Na (sodium) closely resembles lithium (Li) as both elements belong to the same group on the periodic table and share similar chemical properties such as reactivity and the ability to form compounds with other elements.
What pair of elements has the most similar chemical properties?
The pair of elements with the most similar chemical properties are lithium (Li) and sodium (Na). They belong to the same group in the periodic table (Group 1) and exhibit similar reactivity and chemical behavior due to having one valence electron.
What group of elements is Na in?
Sodium is in the group 1 (alkali metals).
What are two elements with one electron in their outer shells?
Any two of the alkali metals, group I of the periodic table: Li, Na, K, Rb, Cs and one extra: the only non metal in group I Hydrogen (H2).
When Na forms an ion it loses its outer electron to become Na what element does Na resemble?
I think you lost some formatting there. Na+ is isoelectronic with neon, if that's what you were trying to ask.
Elements that have the same number of valence electrons are?
Elements that have the same number of valence electrons are found in the same group of the periodic table. For example, all elements in Group 1 (e.g. H, Li, Na) have 1 valence electron, while elements in Group 18 (e.g. He, Ne, Ar) have 8 valence electrons. Valence electrons determine an element's chemical properties and reactivity.
Do the elements Na Mg Al Si P S Cl Ar have anything in common?
All of these elements belong to same period. The period number is 3.
What elements would show similar characteristics to Na?
Na (sodium) belongs to the first group (vertical row) in the periodic table, all of the other elements in this group (row) have similar characteristics to each other. In general, each group has similar characteristics.
Are the elements sodium magnesium and silicon in the same period of elements?
No, the elements sodium (Na) and magnesium (Mg) are in Period 3, while silicon (Si) is in Period 3 in the periodic table of elements. Sodium is in group 1, magnesium is in group 2, and silicon is in group 14.
What three elements have the most similar physical and chemical properties?
Magnesium, strontium , and barium belong to group 2A of the periodic table. These have two valence electrons in their outermost shell. So these three elements have similar chemical properties. But the other given elements do not lie in same group so they have different chemical properties.
