What is the unknown substance if it is determined that is has 55 protons 57 neutrons and 1 valence electron?
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.

What substance has electrons but no protons?
an electron smallest atom is hydrogen...1 proton and 1 electron
Does the electron cloud contain proton's or neutrons or electrons?
This question doesn't technically have an answer. The electron cloud simply surrounds the nucleus and contains the electrons. Each atom of different elements has a different number of protons. It is not determined by the electron cloud. An electron cloud doesn't have a nucleus as the question implies either. An electron cloud odes not contain protons either. Just electrons, as the name suggests.
How many protons electron sand neutrons?
How is this a question.
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
What is the name of the substance in which protons and neutrons are built?
ether

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.
How many protons electron and neutrons does oxygen?
Oxygen is a p block element. It has 8 protons and neutrons.
Do protons or neutrons have negative charges?
Neither (protons are positive and neutrons are neutral).an electron has a negative charge

Is a nucleus made up of protons and electrons or electrons and neutrons or protons and neutrons?
The nucleus is made up of protons and neutrons; the electrons form electron shells around the nucleus.
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
Which particles determine the mass of an atom?
The atomic mass unit is defined to be 1/12 of the mass of a carbon-12 atom. Atomic masses can determined by weighing molar amount of an isotope. Absolute masses (in kg) are determined by measuring the amount that charged atoms are deflected by magnets, since if you know the charge you can calculate mass from the amount of deflection.
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,
