Which element has 5 protons 7 neutrons 5 electrons and a mass of 12?
protons are always the atomic number so if it has five protons it would beee boron
How many protons and neutrons are there in C-12 isotopes?
The C-12 isotope has 6 protons and 6 neutrons.
How many protons neutrons and electrons are in sodium?
elecrons - 11 neutrons - 12 protons - 11
How many protons are there in the c-12 isotope how about the number of neutrons?
6 protons 6 neutrons
How many neutrons are in magnesium 25?
25 is the number of protons and neutrons added together. The atomic number of Mg is 12 which is the number of protons. So 25 - 12 = 13 neutrons.
Why does boron-11 have 5 protons and 5 neutrons?
Boron-11 is an isotope. The atomic number of Boron is 5 which means it has 5 protons, (if there were more or less protons the element wouldn't be boron). the isotope number (11) is the number of protons plus neutrons. to find out the number of neutrons you would take take the isotope and subtract it by number of protons (11-5) which yields 6. To find the isotope add the number of protons to the number of neutrons.
What is the identity of an element with 5 protons 7 neutrons and 5 electrons?
Five protons makes this the element boron. The number of protons is the atomic number, and determines the identity of an element. This example would be the boron-12 isotope because it contains 5 protons and 7 neutrons.
How many protons and neutrons are there in atom of carbon 12?
Carbon 12 has 6 protons and 6 neutrons.

How many protons have magnesium?
12 protons, 12 electrons, 12 neutrons
How many protons and neutrons are there in C-12 isotopes?
The C-12 isotope has 6 protons and 6 neutrons.
How many protons neutrons and electrons are in sodium?
elecrons - 11 neutrons - 12 protons - 11
How many protons are there in the c-12 isotope how about the number of neutrons?
6 protons 6 neutrons
How many protons neutrons and elecrons are in carbon?
protons: 6 electrons: 12 neutrons: 6
How many proton in c-12 and neutrons?
Carbon 12 has 6 protons and 6 neutrons. The amount of neutrons is exactly the same as the amount of protons.
How many neutrons are in magnesium 25?
25 is the number of protons and neutrons added together. The atomic number of Mg is 12 which is the number of protons. So 25 - 12 = 13 neutrons.
How many protons neutrons and electrons does soduim have?
Sodium has 11 protons, 11 electrons and 12 neutrons.
