What else can I help you with?
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 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 element is a nonmetal in period 3 atomic mass 12?
No element in period 3 has an atomic mass of 12.
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 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 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 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.
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
What is period 4 lowest mass?
In the periodic table, period 4 elements have atomic numbers ranging from 19 (potassium) to 36 (krypton). The element with the lowest mass in period 4 is potassium (K), which has an atomic number of 19 and an atomic weight of approximately 39.1 atomic mass units.
What happens to the atomic number as you move across a period?
.The atomic mass increases
