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 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 digit is in the tenths column of 66.4?
The 4 is in the tenths column.
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.
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 elements are found in Group 1A sometimes referred to as Group 1?
Potassium and Hydrogen
How many valence electrons does a group 1A metal atom have?
they all have one valence electron.
What is the group that hydrogen is in?
Hydrogen is in group 1 of the periodic table, also known as the alkali metals group.
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.
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.
How is the ionic charge of a group 1A 2A or 3A ion determined?
The ionic charge of a group 1A, 2A, or 3A ion is determined by the number of electrons lost or gained to achieve a full valence shell. Group 1A ions lose 1 electron to attain a +1 charge, group 2A ions lose 2 electrons for a +2 charge, and group 3A ions lose 3 electrons for a +3 charge.
What is 1 to the power of 2 plus 1a-1a plus 1?
12 + 1a - 1a + 1 = 1 + 0 + 1 = 2
What do atoms in group 1A have?
Atoms in Group 1A (also known as Group 1 or alkali metals) typically have one electron in their outermost shell. This gives them a tendency to form +1 cations by losing this electron to achieve a stable electron configuration. Group 1A elements include lithium (Li), sodium (Na), potassium (K), and others.
Mendeleev's name for a column of elements?
mendeleev's name for a column of elements was groups.
What is the number of valence electron for all the elements in periodic table group 1A 1?
Group 1A (1) elements in the periodic table all have 1 valence electron. This includes elements like hydrogen, lithium, sodium, and potassium.
