The atomic number increases but the atomic mass stays the same?
The atomic number increases but the atomic mass stays the same after the emission of a beta particle by a radioactive atom.
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
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 happens to atomic radius as you move from bottom to top of the periodic table?
atomic radius decreases from bottom to top of the periodic table.
What element has the symbol Ba?
Ba on the periodic table is Barium and its atomic number is 56
What happens to the number of electrons in an atom when the atomic number increases?
The atomic number is specific to the element itself - not the quantity. It does not change as you add in more of the element.
The atomic number increases but the atomic mass stays the same?
The atomic number increases but the atomic mass stays the same after the emission of a beta particle by a radioactive atom.
How does atomic radius increases in the periodic table?
atomic radius increases down a group as the number of shells increases
What physical trends for atomic number versus covalent radius?
Overall as atomic number increases covalent radius increases.
What element has the atomic number six?
Ba - Barium
What is the atomic number of barium?
Barium, with the chemical symbol Ba, is the chemical element with the atomic number 56.
Why nuclear charge increases when atomic number increases across a period?
Atomic number is the number of protons in the nucleus. The higher the number the higher the nuclear 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.
As you travel down a group the do atomic size increases or decreases?
it increases: for the atomic number indicates the number of protons and neutrons in the atom; these are the weight carrying particles
Which element has atomic number of 56 and mass number of 137?
Barium (Ba)
What does the number of electrons in an atom do as the atomic number increases?
Increase
