What is the atomic number of barium?
Barium, with the chemical symbol Ba, is the chemical element with the atomic number 56.
What happens to the atomic number as you move across a period?
.The atomic mass increases
What happens to the atomic mass number as you move across the periodic table?
The atomic mass number generally increases as you move across the periodic table from left to right. This is because the number of protons in the nucleus increases as you move to elements with higher atomic numbers.
When the elements on the periodic table are arranged by increasung atomic number the atomic mass generally increases as the atomic number increases. for some elements however the atomic mass of the el?
It is difficult to be sure what the question is about because it has been truncated.However, it is true that the atomic mass (or standard atomic weights) increases with atomin number. There are, of course, isotopes of elements with a low atomic number which are heavier than atoms of higher atomic number. But there are some examples where the average mass is not in the expected sequence.
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.
How does atomic radius increases in the periodic table?
atomic radius increases down a group as the number of shells increases
What is the atomic number of barium?
Barium, with the chemical symbol Ba, is the chemical element with the atomic number 56.
What element has the atomic number six?
Ba - Barium
Which atom is larger Be or Ba?
Barium (Ba) is larger than Beryllium (Be) because as you move down a group on the periodic table, the atomic size increases. Barium is in a lower group than Beryllium and therefore has a larger atomic size.
What happens to the number of electrons in an atom when the atomic number increases?
When the atomic number increases, the number of protons in the nucleus also increases. Since atoms are electrically neutral, the number of electrons in the atom would also increase to match the number of protons, maintaining a balanced charge.
What increases on the periodic table?
The atomic number increases. The atomic number identifies a particular element and the elements are arranged in increasing order on the periodic table. Also, the atomic weight generally increases as well.
What does the number of electrons in an atom do as the atomic number increases?
Increase
Towards the bottom of the periodic table does the atomic mass increase or decrease?
Towards the bottom, atomic mass increases. Atomic number also increases.
What number increases in the periodic table?
The atomic number increases in the periodic table. The atomic number represents the number of protons in the nucleus of an atom, and it increases by one as you move from left to right across a period on the periodic table.
What happens to the atomic number as you move across a period?
.The atomic mass increases
What happens to the electron configuration as the atomic number increases?
the elctron configuration increases
What happens to the atomic mass number as you move across the periodic table?
The atomic mass number generally increases as you move across the periodic table from left to right. This is because the number of protons in the nucleus increases as you move to elements with higher atomic numbers.
