how many protons neutrons and electrons does silicon 30 have?
434104
There of fourteen protons and 6teen neutrons in 30 Si and the atom is a steady isotopic of silicon .

Here, mass number is 27 and there are 14 neutrons hence protons=27-14=13. In a neutral atom, number of protons=number of electrons. Hence in this case the number of electrons in the neutral atom will be 13. Now, since the atom carries +3 charge hence it will have 13-3=10 electrons.

The copper atom has 29 protons in its nucleus with 29 electrons orbiting the nucleus.

Explanation: Boron has 5 protons, 5 neutrons and 5 electrons. The atomic number (also known as the proton number) of Boron is 5 as it has 5 protons. It has a mass number of 10, as protons and neutron have a relative atomic mass of 1 each, and a neutral charge, as there are equal numbers of +1 protons and −1 electrons.

Iodine has 53 protons and 53 electrons (because it has no charge the number of protons equals the number of electrons). Iodine-131 has 131 protons and neutrons. Iodine-131 has 131 minus 53 protons = 78 neutrons. 5.

Step 1: The atomic number of silicon is 14 so it has 14 electrons in it. Step 2: The electronic configuration of silicon is as follows: Step 3: The highest principal energy level is 3 so the electrons present in 3s and 3p orbital are the valence electrons. So there are 4 valence electrons in silicon atom.

Since 1 mole of silicon contains 6.023 x 10^23 atoms, 4 moles will contain: (4 moles) x (6.023 x 10^23 atoms) = 2.4092 x 10^24 atoms. Thus, 4 moles of the silicon element contains about 2.4 x 10^24 atoms.

For example, a lithium atom (Z=3, A=7 amu) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom), and four neutrons (7 – 3 = 4).

It has two electrons in its first shell, eight electrons in the second shell, and four electrons in the third shell. Since the electrons in the third shell are the outermost electrons, silicon has four valence electrons.

27 protons, 33 neutrons, 27 electrons The cobalt atom has 27 protons as seen in the periodic table. There are also 27 electrons because the charge is 0. There are 33 neutrons because 60-27 = 33.

Ag+ = 47 electrons - 1 electron = 46 electrons. Finally: 47 protons , 61 neutrons and 46 electrons.

We can determine this two ways. The element with 15 protons, meaning it has atomic number 15, is phosphorus. Phosphorus is in group 15/VA. Based on its group number, phosphorus has 5 valence electrons, as do all of the elements in that group.
