What is 1a plus 1b?
1a + 1b because they are different terms and could not be added together. But 1a × 1b would be 1
What is 3a divided by 1a?
3
What is 2 divided by 2a?
1
What digit is in the thousands column of 0.621?
There is no digit in the thousands column. There is a 1 in the thousandths column.
What digit is in the hundredths column of 1569?
1569 Does NOT have a hundredths column. NB However '1' is in the 'thousands' column '5' is in the 'hundreds' column (NB Note the spelling) '6' is in the 'tens' column '9' is on the 'units' column. When 'th' is used in the name it refers to the decimal position. In '1569' there is no decimal position.
What is the group name of column 1 on the periodic table?
The group name of column 1 is alkali metals. They are metallic and basic in nature.
What elements are found in Group 1A sometimes referred to as Group 1?
Potassium and Hydrogen
Where is alkali metals located on the periodic table and their group number?
The alkali metals are group 1, also known as group 1A.
What are the most active metals in group 1A increases?
The reactivity of the alkali metals increases as you go down column 1 (or 1A) in a periodic table. This occurs because the first ionization energy of the metals decreases, as a result of "shielding" the outermost electrons from the attraction of the positive nucleus by the inner electrons.
How is the ionic charge of a group 1A 2A or 3A ion determined?
the group 1a has a positive charge which means it looses 1(-1) to become a noble gas and group 2a has positive 2 which means it looses 2(-2) to become a noble gas and so on
What is 1 to the power of 2 plus 1a-1a plus 1?
12 + 1a - 1a + 1 = 1 + 0 + 1 = 2
Which element has one valence electrons?
Any element in group 1
What is the evidence that suggests that hydrogen should be in the first column of the periodic table?
Hydrogen is a unique element of the Periodic Table. Due to its similarities in properties it can be placed at the top of group 1A or 4A or 7A.
What column number on the periodic table are elements called alkali metals?
This is the group 1.
What family or column is lithium found in the periodic table?
Lithium on the periodic table is found in the first group or family and the second period. The first family is often called the alkali metal family.
When atoms from Column I (Group 1) combine with atoms from Column VII (Group 17)?
These obtained compounds are halides, ionic compounds.
What is the term of Group in the periodic table?
A group is a vertical column on the periodic table. In the past, they were labeled 1A, 2A all the way up to 8A for the noble gases with the transition elements being labeled using 1B, 2B, etc. in the United States. Recently, the IUPAC has numbered the groups as 1-18. For the representative elements, the ones column of the group number delineates the number of valence electrons in the atoms of each element.
