The number on top tells you how many nucleons (protons + neutrons) you have (this usually, also adds up to the molar mass of this specific isotope). … In the case of Krypton-84, this means that you
have 84 nucleons
, where 36 of these are protons, and the remaining 48 are neutrons.

How many electrons does krypton-84 have?
We are given with the atomic number (36) which means that we have 36 protons and
36 electrons
. Using this information, we can get the number of neutrons. Recall that mass number is equal to the sum of the protons and neutrons in the atomic nucleus. Therefore, there are 48 neutrons in Krypton-84.
What would be the number of proton of Krypton if its mass number is 84 and its atomic mass is 36?

What makes Krypton unique?
It’s not just Superman’s home planet; Krypton is one of the
rarest gases
on Earth, composing only 1 part per million of the atmosphere by volume. This noble gas is colorless and odorless. It has a full outer shell of electrons, rendering it largely inert to reactions with other elements.
Is Krypton a real element?
krypton (Kr), chemical element, a
rare gas of Group 18 (noble gases)
of the periodic table, which forms relatively few chemical compounds. About three times heavier than air, krypton is colourless, odourless, tasteless, and monatomic.
What is krypton-85 used for?
Radioactive krypton, Kr-85
1
, has been used for
measuring the rate of rare-gas clean-up in pre-T.R. valves
, with promising results. Krypton-85 has a half-life of ten years and emits mainly beta radiation (680 keV.) and some gamma radiation (500 keV.).
What is the charge of krypton?
This results in an anion with 35 protons, 36 electrons, and a
1− charge
. It has the same number of electrons as atoms of the next noble gas, krypton, and is symbolized Br
−
.
What element has a mass of 84?
The mass number of common
krypton
is 84, and its atomic number is 36.
What are the first 30 elements?

What do you call the element from atomic number 57 71?
The elements from atomic number 57 to 71 are called
Lanthanides
. They are called lanthanides, since lanthanum is chemically identical to the elements in the sequence. … The lanthanides are between Barium and Hafnium.
