Answer:
B)
. six electrons in the triple bond of diatomic nitrogen
Explanation:
The three line in this Lewis dot structure represents the six electrons in the triple bond of diatomic nitrogen.
Nitrogen is made up of 7 electrons with 5 valence ones.
A lewis structure is made up of the symbol of the element surrounded by dot to represent the valence electrons.
In this nitrogen molecule, both species share 6 electrons. This makes each nitrogen atom isoelectronic with neon.
Answer:
chlorine
Explanation:
Because in periodic table across the period from left to right, ionization energy increases due to increase in the nuclear charge as more and more electrons are added to the same shell.
Explanation:
The fundamental particles in an atom are protons, neutrons and electrons. The given atoms are called the isotopes of magnesium. They only differ in the number of neutrons they possess.
Protons are the positively charge particles in an atom
Neutrons occupy the center of an atom with protons and they carry no charges
Electrons orbits an atom and they carry no charges.
For a neutral atom, the number of protons and electrons are the same.
Magnesium - 24
Magnesium - 25
Magnesium - 26
Magnesium is an atom on the periodic table with an atomic number of 12.
The atomic number is the number of protons in an atom.
The numbers in front of the problem given are the mass numbers.
For neutral atoms;
Number of protons = number of electrons = atomic number
Number of neutrons = Mass number - atomic number
Magnesium - 24
Protons = 12
Electrons = 12
Neutrons = 24 - 12 = 12
Magnesium - 25
Protons = 12
Electrons = 12
Neutrons = 25-12 = 13
Magnesium - 26
Protons = 12
Electrons = 12
Neutrons = 26 - 12 = 14

Answer:
The table tennis balls represent neutrons that are released when the nucleus splits and cause other nuclei to split
Explanation:
Nuclear fission is defined as the separation of a nucleus into two smaller nuclei.
It takes a neutron to set off a nuclear fission reaction. When that occurs, neutrons are released and those neutrons in turn are what set off other nuclear fissions. This is defined as a Nuclear Fission Chain Reaction. In the model, the one tennis ball that will be thrown will be modeled as the starting neutron that sets of the initial (first) fission. The mouse traps with tennis balls represent the other nucleuses waiting to be struck by the one tennis ball. Once the initial tennis ball strikes the first mouse trap, that mouse trap will release its tennis ball hitting others and continuing the cycle.
It can also be modeled as such:
1. %yield = actual yield / theoretical yield x 100
= 3 g / 4. 46 g x 100
= 62.11 % percent yield
