What ar the three smaller subatomic particles that make up an atom?
A electron(s) in a orbital around a nucleus made of protons and neutrons.
How many protons and neutrons are in Ar with a mass number of 36?
18 protons and 18 neutrons
How many argon atoms are there in 1.5 102 g of argon?
2.3 × 1024 atoms of Ar
Which has more atoms—a dozen H atoms or a dozen Ar atoms?
9
What element's neutral atoms have 20 protons?
it is about the atomic number. Calcium is the element.
Which of these is not a fundamental subatomic unit of an element protons nucleus electrons neutrons?
Protons and neutrons ar fomed from quarks and are not considered as fundamental particles; they are components of the atomic nucleus.
What is the difference between a neutron and a nucleus?
Well a neutron and a nucleus are different from each other because a neutron is a particle within the atom nucleus with a neutral charge The nucleus however is all the neutrons and the protons. Nucleus could also mean the nucleus of a cell, which is commonly refered to as well, but is completely different.
Why modern periodicity consist the protons of any atom?
In the periodic table chemical elements ar listed after the number of protons in the atomic nucleus.
What ar the three smaller subatomic particles that make up an atom?
A electron(s) in a orbital around a nucleus made of protons and neutrons.
How many argon (Ar) atoms are there in 1.5 102 g of argon?
2.3 × 1024 atoms of Ar
How many atoms are there in Ar?
one
How many protons neutrons and electrons are in Ar?
18 protons and electrons and 22 neutrons.
What is the nucleus of argon?
The nucleus contains 18 protons and neutrons. The number of neutrons depends on the isotope of argon. Ar-20, the most common isotope of argon has 22 neutrons.
Why are electrons in the 1s subshell much closer to the nucleus in Ar than in He?
It is due to the increased in the effective nuclear charge in argon. Helium has 2 protons in its nucleus. On the other hand, argon has 18 protons in its nucleus.Therefore, it has greater attractive power. Due to this, all the electrons are pulled closer to nucleus.
How many protons and neutrons are in Ar with a mass number of 36?
18 protons and 18 neutrons
How many protons neutrons and electrons in 40 Ar?
18 protons 18 electrons 22 neutrons
How many atoms ar ein 133g of calcium?
The number of atoms is approx. 19,98.10ex.23
