What else can I help you with?
What do you predict the trend in atomic mass will be going down a group?
The atomic mass increases down a group.
What is the general trend that you observe from a graph that plots atomic number vs atomic mass?
The general trend observed is that as atomic number increases, atomic mass also increases. This relationship is due to the fact that atomic number corresponds to the number of protons in an atom's nucleus, which in turn contributes to its mass.
What is the trend from left to right for atomic mass on the periodic table?
The atomic weight (not mass) increase from left to right in a period.
What is the exception to the atomic mass trend in period 4?
The exception to the atomic mass trend in period 4 of the periodic table is the reversal in atomic masses between argon (Ar) and potassium (K). Potassium has a higher atomic mass than argon, which is contrary to the trend of increasing atomic mass from left to right seen in the other elements of period 4.
What is the trend in atomic mass going down a group?
The atomic mass will increase. As you go down a group in the periodic table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
What trend can be identified on the periodic table?
One trend that can be identified on the periodic table is the periodicity of elements, which refers to the repeating patterns of properties such as atomic number, atomic mass, and chemical reactivity across rows and columns.
Can atomic mass increases be used to describe rows or columns in the periodic table?
Atomic mass increases primarily describe the trend across periods (rows) in the periodic table, as elements in the same row have increasing atomic numbers and generally higher atomic masses. In columns (groups), atomic mass can also increase, but the trend is less consistent due to varying electron configurations and isotopes. Therefore, while atomic mass can provide some insight into both rows and columns, it is more straightforwardly applicable to horizontal trends across periods.
Does the atomic mass decrease as you move down a group?
No, the atomic mass generally increases as you move down a group in the periodic table. This is because each successive element has more protons and neutrons, leading to a higher atomic mass. While there may be exceptions due to isotopes or specific elements, the overall trend is an increase in atomic mass down a group.
How can the atomic mass of the element be lower than the element that came before it?
Because the periodic table is organized by atomic number, not by atomic mass. The general trend in the periodic table is a higher atomic mass as you go up atomic number, but there are exceptions.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
What statement accurately compares the trends in atomic number and atomic mass in the period gave?
In a period of the periodic table, atomic number increases sequentially from left to right as protons are added to the nucleus of each successive element. Atomic mass typically increases as well, although it does not always correlate directly due to the varying number of neutrons in isotopes. While atomic number defines the identity of an element, atomic mass reflects both protons and neutrons, leading to a generally increasing trend in mass alongside the atomic number across a period.
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
