What is the unknown substance if it is determined that is has 55 protons 57 neutrons and 1 valence electron?
Nettyflores
It is a Cesium isotope, with the Atomic Mass of 112.
It could also be an ion depending on how many total electrons it has.

Atomic mass of an atom is determined by the combined masses of?
the atomic mass is determined by adding the weight of protons & neutrons
Where are protons and neutrons found in an electron?
Protons and neutrons are not in electrons. protons and neutrons are the center or core of an atom. the electron(s) is/are found in a "cloud" along the outside edge of the atom. Hydrogen for example has 1 proton at its center and 1 electron floating around it keeping it neutral.
How many protons electron sand neutrons?
How is this a question.
What is determined the mass of an atom?
Protons, neutrons and electrons
What does protons and neutrons have in common?
the protons are positively charged that's how you know if it is a proton or an electron because a electron has a negative charge
How many protons and neutrons are in chlorine and sodium'?
The number of protons and neutrons is not changed; sodium lose one electron and chlorine gain an electron.
Atomic mass of an atom is determined by the combined masses of?
the atomic mass is determined by adding the weight of protons & neutrons
Do protons or neutrons have negative charges?
Neither (protons are positive and neutrons are neutral).an electron has a negative charge
How many protons electron and neutrons does oxygen?
Oxygen is a p block element. It has 8 protons and neutrons.
Protons and neutrons are?
Protons and Neutrons make up the nucleus of an atom Protons are positively charged, neutrons are neutral. Electron circle the nucleus and a negatively charged.
Where are protons and neutrons found in an electron?

What is an electron cloud made of?
An electron cloud is made up of protons and neutrons.
Where is each subatomic particle located in a atom?
electron - electron cloud protons and neutron- nucleus
Where are Protons Neutrons and Electron found?
The protons and neutrons are located in the atomic nucleus; the electrons are around the nucleus, arranged in shells,
