Radium (atomic no. 88): Group 2 (Alkaline Earth Metals), period 7 of the Periodic Table of elements.
What else can I help you with?
Consider the group 1A element sodium (atomic number 11) the group 3A element aluminum (atomic number 13) and the group 7A element chlorine (atomic number 17). These elements are in period 3. How are?
This is a consequence of the law of periodicity of chemical elements.
What does the number of nucleus tell you about the element?
The number of the protons in the nucleus of a chemical element is equivalent to the atomic number; the atomic number define the position of this element in the periodic table (group, period). And from these we can suppose the chemical properties of this element.
What happens to the atomic number as you go down the group?
The atomic number increases as you go down a group on the periodic table. This is because each element in a group has one more electron and proton than the element above it, leading to an increase in atomic number.
What is the period number for the element platinum?
Platinum is present on period 6 and group 10.It is represented by symbol Pt.It has atomic number of 78.
What is the period and group for lutetium?
Lutetium is a chemical element with the symbol Lu and atomic number of 71. It has a period of 6 and belongs in the Lanthanide group.
Which element is in group 17 of period 3?
Chlorine belongs to group 17 of period 3.It belongs to Halogens group with atomic number 17.
What is the element which belongs to the third group and third period?
The element belonging to the third group and third period is aluminum (Al). It has an atomic number of 13.
Consider the group 1A element sodium (atomic number 11) the group 3A element aluminum (atomic number 13) and the group 7A element chlorine (atomic number 17). These elements are in period 3. How are?
This is a consequence of the law of periodicity of chemical elements.
What element is in group 1 period 3?

What element is found in group 14 period 2?
what element is found between period 2 and group 14
What does the number of nucleus tell you about the element?
The number of the protons in the nucleus of a chemical element is equivalent to the atomic number; the atomic number define the position of this element in the periodic table (group, period). And from these we can suppose the chemical properties of this element.
What element is in period 4 group 15 of the periodic table?
Element Name: Arsenic. Chemical Symbol: As.
What happens to the atomic number as you go down the group?
The atomic number increases as you go down a group on the periodic table. This is because each element in a group has one more electron and proton than the element above it, leading to an increase in atomic number.
What does the period number on a periodic table represent?
the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.
What element is found in period 2 and group 13?
Boron is the element. Its symbol is B.
What is the element in period 4 and group 6?
