Yes, the objects velocity can change direction
In an alpha decay, an atom emits an alpha particle. An alpha particle consists of 2 protons and 2 neutrons: this means that during this kind of decay, the original atom loses 2 protons and 2 neutrons from its nucleus.
This also means that the atomic number Z of the element (the atomic number is the number of protons in the nucleus) decreases by 2 units in the process, while the mass number A (the mass number is the sum of the number of protons and neutrons) decreases by 4 units.
My device will use either radio waves or light waves.
Those are the only EM waves I'm equipped to generate.
If I want to get elegant about it, I may use radio waves with
frequencies around 14.1 MHz, because those can be received
many thousands of miles away. I know how to build an effective
antenna to radiate at that frequency, and as a licensed ham-radio
operator, I can do it legally.
Answer:
periods 3-5
Explanation:
If you know your periodic table well, this is simple. but to explain it, periods 3-5 have elements that have electrons that fill the s, p and d orbitals. if you do not know, the s orbital starts off with the first period and the second period until you get totto the right side which is where the o block starts. the block is all of the transition metals and they all fill the s and p or ital as well.
