Atoms of beryllium-7 decay by grabbing electrons from their surroundings. The rate of this kind of decay depends on the chance of an electron straying into the nucleus and getting absorbed. So increasing the density of electrons surrounding the atomic nucleus can speed up the decay.
Q. What does each column represent in the periodic table?
The columns of the table represent groups, or families, of elements. The elements in a group often look and behave similarly, because they have the same number of electrons in their outermost shell — the face they show to the world.

Q. What numbers mean on periodic table?
What do the symbols and numbers mean? When you look at the periodic table, the symbols and numbers look like the image on the left. This is the total number of protons and neutrons in an atom. The number below the symbol is the atomic number and this reflects the number of protons in the nucleus of each element’s atom.
Q. Can atoms be broken down by chemical means?
consists of atoms of two or more different elements bound together, can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means), has properties that are different from its component elements, and. always contains the same ratio of its component atoms.
Q. Can you predict when an atom will decay?
This process changes the atom to a different element or a different isotope. It is impossible to predict when an individual radioactive atom will decay. The half-life of a certain type of atom does not describe the exact amount of time that every single atom experiences before decaying.
Q. How do you predict decay mode?
In terms of decay types, beta decay is predicted by looking at an isotope’s neutron to proton ratio. Alpha decay will occur frequently in elements with atomic numbers greater than 83, and gamma decay will occur when a nucleus is an excited state.
