Is the atomic mass on the bottom or top?
At the bottom, the atomic number is at the top.
What happens to the atomic size from the top to the bottom of the periodic table?
The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
. How does atomic radius change from top to bottom in a group in the periodic table?
It tends to increaseThe atomic radius increases down the group
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.
Which of these describes atomic radii as one moves from top to bottom within a group?
The atomic radius increases from top to bottom within a group.
Is the atomic mass on the bottom or top?
At the bottom, the atomic number is at the top.
What happens to the atomic number from top to bottom in a column?
The atomic number at the top is always less than the atomic number at the bottom of the column
What is the difference between atomic mass unit and atomic mass?
Atomic mass unit is the number on the bottom of the Chemical. However, the atomic mass is the number on the top of the chemical minus the number on the bottom. b.t.w The no. of neutrons = top no. minus bottom no.
What happens to the atomic size from the top of the periodic table to the bottom?
The atomic size increase from top to bottom of Periodic Table. As the number of shells increases from top to bottom, the atomic size increases.
What happens to the atomic size from the top to the bottom of the periodic table?
The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
How does the atomic number change across a column of the periodic table?
Columns are vertical, so you are referencing a group of elements. The atomic number increases as you descend from top to bottom. Rows are horizontal, which references the periods. The atomic number increases as you go from right to left.
How many neutrons are in alumnium?
14 - Subtract atomic mass(usually bottom #) from atomic number(usually top #).
What happens to the atomic number as you move down the alkal metal group?
The atomic number increases, because as you move from top to bottom, you are adding protons to the nucleus, and atomic number is the number of protons.
How does the atomic number change as you move left or right of the periodic table?
left to right - increases (by 1s)right to left - decreases (by 1s)top to bottom - increases (big steps)bottom to top - decreases (big steps)
Are protons the number on top or the bottom?
For a given isotope of an element, the "top number" (e.g. 14C or carbon-14) is the atomic mass number, the total of neutrons and protons. The bottom number, if displayed, is the atomic number (e.g. 6C all isotopes of carbon have 6 protons). To find the number of neutrons, subtract the atomic number from the isotopes atomic mass number. Here, 14C will have 8 neutrons, and the result is that it is an unstable radioactive isotope. Many stable elements, however, have many more neutrons than protons.
. How does atomic radius change from top to bottom in a group in the periodic table?
It tends to increaseThe atomic radius increases down the group
The stranded atomic notation for an atom that has an atomic number of 4 and 5 neutrons?
It would be 9 on top, 4 on bottom and then Be.
