How do you find the mass of Si-28?
We’re given the following values:
- Atomic Mass = ?? amu.
- Silicon-28: Mass = 27.9769 amu f.a. = 92.18% ÷ 100 = 0.9218.
- Silicon-29: Mass = 28.9765 amu f.a. = 4.71% ÷ 100 = 0.0471.
- Silicon-30: Mass = 29.9738 amu f.a. = 3.12% ÷ 100 = 0.0312.

What is the difference between 28 Si and 29 Si?
Explanation: The abundance of Si-28 is 92.23%. Si-29 is 4.68% and Si-30 is 3.09%. Because most Si atoms have a mass of 28 amu, the average mass of all silicon atoms is very close to 28.
How do u find neutrons?
To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
How many neutrons does silicon have?
14 neutrons
For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28.
Is Si-28 an isotope?
Three stable isotopes of silicon are known: silicon-28, which makes up 92.21 percent of the element in nature; silicon-29, 4.70 percent; and silicon-30, 3.09 percent. Five radioactive isotopes are known. Elemental silicon and most silicon-containing compounds appear to be nontoxic.

How many protons does tungsten have?
74
Tungsten/Atomic number
Tungsten contains exactly 74 protons in its nuclear makeup. This number of protons is unique to Tungsten as no other element shares this amount of protons. For this reason, tungsten has an atomic number or proton number of 74. An atom will have the same amount of electrons as it does protons.
How many protons and how many neutrons are in the most abundant isotope of SI?
1 atom of silicon has 14 protons, 14 neutrons (in its most abundant isotope, silicon-14 ), and 14 electrons.
How many protons does calcium have?
20
Calcium/Atomic number
So Ca (Calcium) looses two electrons, what will be the resulting charge? Ca has 20 protons, so neutral it would have 20 electrons, but according to the charge, 2 electrons have been lost.
What element has 15 protons in its nucleus?
phosphorus
Atomic number of phosphorus = 15. So phosphorus has 15 protons and 15 electrons.
How many protons does neon 10 have?
ten protons
Neon is an atom with atomic number ten. Its atomic weight is 20.179 which cause it to have ten neutrons and ten protons in its nucleus and ten electrons outside. Neon; Neon, Ne, is a colorless inert noble gas and it is also the second lightest noble gas.
What has 14 protons in the nucleus?
silicon
For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28.
How do you find protons?
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
