What is the d block element with the smallest atomic number?
Scandium. Its atomic number is 21. It is the first d block element.
When an isotope undergoes alpha decay which of the following change A The name of the element B The atomic number C The mass number D All of these change?
D. All of these change. In alpha decay, an isotope emits an alpha particle, which consists of two protons and two neutrons, leading to a decrease in the atomic number and mass number of the parent isotope. This results in the formation of a new element with a different name, atomic number, and mass number.
Where is the atomic mass located?
The atomic mass of an element is located below the element's symbol in the periodic table. It is typically shown as a decimal number. The atomic mass represents the average mass of an atom of that element, taking into account the different isotopes and their relative abundance.

If the atomic number of element D is 20 then what is the atomic number of element R?
34
What is the d block element with the smallest atomic number?
Scandium. Its atomic number is 21. It is the first d block element.
If the atomic number of Element D is 20 then what is the atomic number of R?
If the atomic number of Element D is 20, then Element D is calcium (Ca). The atomic number of calcium is 20, so R would also have an atomic number of 20. This means that R would also be calcium (Ca).

Atomic number of it is 79.Gold is a d block element. atomic number of gold is 79.
What is the atomic mass or mass number?
The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon atoms, contain six protons and have an atomic number of 6. Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same.
An element has 8 protons 9 neutrons and 8 electrons Its atomic number and atomic mass respectively are A 9 and 16 B 9 and 17 C 8 and 17 D 16 and 8 E 8 and 16?
The element with 8 protons has an atomic number of 8. Adding protons and neutrons gives you the atomic mass, so the element has an atomic mass of 8 + 9 = 17. Therefore, the correct answer is C) 8 and 17.
What is the atomic number if the first element to start filling a d sublevel?
The d suborbitals begin at period 4, but the d-sublevel is actually 3d. The first element is scandium, which has the atomic number of 21.
