What is the nuclear charge in the 4th shell of an argon atom?
The nuclear charge in the 4th shell of an argon atom is +18, as argon has 18 protons in its nucleus. The nuclear charge is equal to the number of protons in the nucleus of an atom.
What is an atomic radius?
Atomic radius is the measure from the middle of an atom to the outter edge. Usually mesured between two atom. Measure from the middle of one atom to the middle of another and then divide by two.
When does the radius of an atom decreases or increases?
The radius of an atom typically decreases when moving from left to right across a period in the periodic table due to increasing nuclear charge. It increases when moving down a group in the periodic table due to the addition of energy levels.
What is the radius of an atom in picometers?
Scandium empirical atom radius: 160 pm Scandium calculated atom radius: 184 pm
Can give you some explanation about the structure of the atom esspecially about it's radius?
The atomic radius is the distance from the nucleus to the outermost electron shell of an atom. Atoms consist of a dense, positively charged nucleus surrounded by a cloud of electrons in specific energy levels or shells. The size of the atomic radius increases as you move down a group in the periodic table due to the addition of electron shells, and decreases as you move across a period due to increasing nuclear charge.
Compared to the atomic radius of a sodium atom the atomic radius of a magnesium atom os smaller the smaller radius is primly a result of the magnesium atom having?
The smaller atomic radius of a magnesium atom compared to a sodium atom is primarily a result of the increased nuclear charge in magnesium due to the higher number of protons. This increased nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller atomic radius for magnesium.
What nuclear weapons depend on fission reactions?
The atom bomb
In nuclear physics what units are used to measure the radius of an atom?
pico meter
What can you determine about an atom based on its Atomic Radius?
the further right you go on the periodic table, the atomic radius decreases. the further down you go on the periodic table, the atomic radius increases. you can determine where an atom is generally placed on the periodic table based on its atomic radius.
What is the nuclear charge of an atom with mass of 23 and an atomic number of 11?
The atomic number of 11 means there are 11 protons in the nucleus, giving the atom a nuclear charge of +11. The atom in question is a Sodium atom.
What is it called when the number of protons in an atom change?
The only way to change the number of protons in an atom is with a nuclear reaction.
What does the mass of an atom depend on?
The number of neutrons and protons in the nucleus of the atom.
Why do atom size decreases in periods instead of increasing due to protonic repulsion?
As we move across the period, there is an increase in the atomic number i.e., there is an increase in the number of protons inside the nucleus. This means, there is more nuclear force. This nuclear force pulls the electron orbits as close as it can. thus, the radius of the atom decreases. Hence the atomic size decreases.
What is the mass number of a atom?
the mass number is number of protons in an atom, plus the number of neutrons.
Which particle determines the nuclear charge?
Protons determine the nuclear charge of an atom. Each proton carries a positive charge and is located in the nucleus of an atom. The number of protons in an atom determines its atomic number and therefore its nuclear charge.
Does a small atom has more energy gap?
Energy gap depends on the energy of a particular energy level at a given radius in analogy with the energy of a hydrogen atom neing directly proportional to atomic number and inversely proportional to the square of nth energy level. It does not depend on the smallness of an atom.
What is the nuclear charge in the 4th shell of an argon atom?
The nuclear charge in the 4th shell of an argon atom is +18, as argon has 18 protons in its nucleus. The nuclear charge is equal to the number of protons in the nucleus of an atom.
