The number of atoms of fluorine that are present in the molecules of CF4 is calculated as follows
1 x4 = 4 atoms of fluorine
in CF4 they are four atoms of fluorine since the subscribe 4 indicate that they are four atoms of fluorine
Answer:
they are indeed very strong
Answer:
17.76 cm x 9.21 cm x 4.45 cm = 727.9 cc. Calculate the weight of the gold bar using the density of gold, which is: 19.3 g/cc. Use the density ...
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
