Do Protons Neutrons or electrons have the most energy?
Electrons have the least amount of energy compared to protons and neutrons. Protons and neutrons have similar amounts of energy in an atom, as they are found in the nucleus and contribute to the majority of the atom's mass.
How many electrons does an element have if it has 17 protons and 18 neutrons?
If an element has 17 protons, it will also have 17 electrons since atoms are electrically neutral. Adding the number of neutrons (18) to the number of protons (17) gives us the mass number of the element, which in this case would be 35.
How many numbers of protons does soduim have?
The sodium atom has 11 protons 11 electrons and 12 neutrons.
How many protons electrons and Neutrons does the element Silicon have?
Atomic number 14 it has 14 protons it has 14 electrons, provided it is a silicon atom and not an ion with -4 charge neutrons here are a variable. i dont know the percentages of each ion, but the atomic mass is 28.08, that rounds to 28, subtract 14 and silicon most commonly has 14 neutrons
Why are the atoms of gold different from atoms of silver?
Silver atoms contain 47 protons, while gold atoms contain 79 protons. They also have different number of neutrons depending on the isotope. The number of electrons in an atom is equal to its number of protons if the atom has no electric charge.

How many protons electrons and neutrons are there in an atom that has an atomic number of 8 and a mass of 15?
Learn that the atomic number means the number of protons. The mass number is the number of protons and the number of neutrons. So if we take the number of protons from the mass number then we get the number of neutrons that are present (mass umber - atomic number = number of neutrons). in this case 15 - 8 = 7. Since you dont mention there is any charge on the atom ill assume that its charge is neutral. For an atoms charge to be neutral then the positive charges from protons must equal the negative charges from electrons and vica versa. So for this to be the case with 8 protons then we must have 8 electrons.
How many numbers of protons does soduim have?
The sodium atom has 11 protons 11 electrons and 12 neutrons.
How many protons nuetrons and electrons does neon have?
Every neon atom has 10 electrons. There are 10 and 12 neutrons in the neon-20 and neon-22 isotopes respectively.
What element has 57 protons and 73 neutrons?
I dont think there is one.
A neutral sodium atom has 11 protons and 12 neutrons in its nucleus How many electrons does a plus 1 sodium ion have?
If you dont know this answer , well i dont either :0
Which two particles make up the mass of an atom?
. . . the two with (appreciable) mass: protons and neutrons.The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.Protons and neutrons.idk dont asqq meehThe sum of the numbers of protons and neutrons determine the mass number. Electrons have negligible mass compared to protons and neutrons.The particles counted are neutrons and protons each having a relative atomic mass of 1. The atomic number is the number of protons.Atomic mass of an atom is the mass of the nucleus.Hence the atomic mass is the sum of the number of protons an neutrons present in the nucleus of the atom. The electrons are not considered as their mass is negligible compared to the mass of the neutrons and protons.
How many protons electrons and Neutrons does the element Silicon have?

If an atom has 15 protons 14 neutrons and 18 electrons what is the atoms electrical charge?
'-3' It is not an atom, when it is a charged species, but an ION. 15 protons (15+) 18 electrons (18-) Hence +15 - 18 = -3 The charge. By the numbers given , this is the element Phosphorus. , which can exhibit a 'P^(-3) ion.
An atom with an atomic number of 9 and a mass number of 19 would have an atomic mass of what?
To find the atomic mass, subtract the atomic number (protons) from the mass number (protons + neutrons). Atomic mass = Mass number - Atomic number Atomic mass = 19 - 9 Atomic mass = 10amu So, an atom with an atomic number of 9 and a mass number of 19 would have an atomic mass of 10 atomic mass units (amu).
