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 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 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 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 happened to atomic mass when across each period?
As you move across a period in the periodic table from left to right, the atomic mass generally increases. This is due to the addition of protons and neutrons in the nucleus, which contributes to a higher mass. However, this trend is not perfectly linear, as variations in isotopes and electron configurations can cause slight fluctuations in atomic mass values. Overall, the increase reflects the addition of heavier elements as you progress across the period.
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 do you predict the trend in atomic mass will be going down a group?
The atomic mass increases down a group.
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 is the general trend in densities for period 2?
The general trend in densities for period 2 elements of the periodic table is that densities increase from left to right. This is because elements in period 2 have increasing atomic numbers, leading to an increase in atomic mass and a decrease in atomic volume, resulting in higher densities.

What is the trend for atomic mass?
It increases as you move to the right or go down
What element is a nonmetal in period 3 atomic mass 12?
No element in period 3 has an atomic mass of 12.
What is the atomic mass of hafnium?
The atomic mass of hafnium is approximately 178.49 atomic mass units.
In general what happens to the atomic mass in each period?
In general, atomic mass tends to increase as you move from left to right across a period in the periodic table. This occurs because each successive element has an additional proton and neutron in its nucleus, contributing to a higher atomic mass. However, the increase is not uniform due to variations in isotopes and the presence of different numbers of neutrons among elements. Overall, the trend reflects the overall increase in the number of nucleons as atomic number rises.
How can you predict the properties of missing elements?
yes, properties of an element depends on its atomic number and atomic mass unless it is an exception and the atomic number and atomic mass of unknown elements are known by placing it in periodic table
