How many protons does an atom have if it looses 2 electrons?
The same number of protons.
An atom has the same number of which 2 particles?
Protons and electrons, given the number of protons and neutrons can vary!
How do you find out how many protons an atom has?
Every element has its own unique atomic number. The atomic number tells how many protons are in 1 atom of that element. Since no 2 elements have the same same atomic number, no 2 elements have the same number of protons. Basically, the atomic # is the same as the # of protons. For example: Aluminum= ''Al'' has an atomic # of 13, so it has 13 protons.
Describe the number of valence electrons in each atom as you move down group 2 in the periodic table?
As you move down group 2 in the periodic table, the number of valence electrons in each atom remains the same, at 2. This is because elements in the same group have the same number of valence electrons, regardless of the period they are in.
How many electrons are on a boron atom?
5- the atomic number of boron is 5. Atomic number is the number of protons and this is the same as the number of electrons in the neutral atom.
Oxygen atom and oxide ion have same?
The oxygen atom and oxide ion have the same number of protons, which is 8. The oxide ion, however, has gained two electrons, giving it a charge of -2, whereas the oxygen atom is neutral.
How many valence electrons does a neutral magnesium atom have?
If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
What could be different about 2 or more atoms of the same atom?
Did you mean, "What could be different about 2 or more atoms of the same element?" If you did, the answer is that they can have a different number of neutrons.
What atom contains 1 electron and 2 protons?
None, for it to be an atom it has the have the same number of electrons and protons. Something with 1 electron and 2 protons would theoretically be a helium ion but helium does not form ions.
What is the electronic structure of an atom with a proton number 5 and a nucleon number 11?
In a neutral atom, the number of electrons is the same as the number of protons. The electronic structure of an atom with five electrons would be 2, 3. The electron configuration would be 1s22s22p1.
What is the number of this atom?
2
Why is any atom neutral?
The atom has the same number of electrons as protons. electrons are negatively charged, and protons are positively charged. So for example in a Helium atom, it has 2 protons and 2 electrons, so the sub-particles cancel out, making the atom neutral.
