PLEASE HELP why does the atomic radius of elements increases when you go down the Periodic Table

Chemistry
1 answer:
vichka [17]3 years ago
3 0
This is caused by the increase in the number of protons and elections across a period. One proton has a greater effect than one election. Meaning electrons are pulled towards the nucleus, resulting in a smaller radius

If one-trillionth of the atoms of a radioactive isotope disintegrate each day, what is the decay constant of the process?
Paul [167]

Decay constant of the process 1×10^(-12) day^(-1).

<h3>What is decay constant?</h3>

A radioactive nuclide's probability of decay per unit time is known as its decay constant, which is expressed in units of s1 or a1. As a result, as shown by the equation dP/P dt =, the number of parent nuclides P declines with time t. Nuclear forces are about 1,000,000 times more powerful than electrical and molecular forces in their ability to bind protons and neutrons. The strength of the bonds holding the radioactive element are likewise indifferent to the decay probabilities and's, in addition to being unaffected by temperature and pressure. The decay constant is related to the nuclide's T 1/2 half-life by T 1/2 = ln 2/.

NEED HELP! what is a orbital . describe
olchik [2.2K]

Answer:

In chemistry and quantum mechanics, an orbital is a mathematical function that describes the wave-like behavior of an electron, electron pair, or (less commonly) nucleons. An orbital can contain two electrons with paired spins and is often associated with a specific region of an atom.
