Which is smallest in size - atom or electron?
An electron is much smaller in size than an atom. An atom consists of a nucleus (protons and neutrons) surrounded by electrons. The size of an electron is much smaller compared to the entire atom.
What is contained inside the nucleus of an atom?
The nucleus of an atom contains protons and neutrons, which are called nucleons. Protons have a positive charge, while neutrons have no charge. Electrons, which have a negative charge, orbit around the nucleus in electron clouds.
How many electrons and protons does 1 atom of oxygen have?
1 atom of oxygen contains 8 protons and 8 electrons.
The of an atom are negatively charged?
Of course it it is. An electron is negative, while a proton is positive. Therefore, by adding an electron, its the same thing as adding a negative. 0 - 1 = -1. So to cut to the chase, adding an electron makes the atom negative.
What is the charge of a sodium atom that has lost 1 electron why?
The charge of a sodium atom that has lost 1 electron is +1. This is because sodium normally has 11 protons and 11 electrons, but when it loses 1 electron, it now has 11 protons and 10 electrons, resulting in a net positive charge of +1.
What is the size order for these scientific particles Proton Neutron Atom Electron Nucleus?
IIRC Atoms (contains Protons/Neutrons and electrons) Nucleus contains Protons and Nuetrons Proton atomic size 1 Nuetron atomic size 1 electron atomic size 1/1836 i.e the proton is 1836 bigger than the electron

The nucleus of an atom contains what two particles?
nucleus....contains protons & neutrons
What is contained inside the nucleus of an atom?

How many electrons and protons does 1 atom of oxygen have?
1 atom of oxygen contains 8 protons and 8 electrons.
What is the charge of an atom with one electron more than protons?
If the atom has more electrons than protons than the atom will be negative.
The of an atom are negatively charged?

What are the positively charged subatomic particles that remain when a hydrogen atom loses an electron?
The positively charged subatomic particles that remain when a hydrogen atom loses an electron are protons. Each hydrogen atom normally contains one proton, and when an electron is lost, the proton remains with a net positive charge.
What is the charge of a sodium atom that has lost 1 electron why?
The charge of a sodium atom that has lost 1 electron is +1. This is because sodium normally has 11 protons and 11 electrons, but when it loses 1 electron, it now has 11 protons and 10 electrons, resulting in a net positive charge of +1.
How many protons neutrons electrons and valence electrons are there in each atom in hno3?
In each atom of HNO3: There is 1 proton in the hydrogen atom, 7 protons in the nitrogen atom, and 16 protons in the oxygen atom. The number of neutrons can vary since it depends on the isotope of each element. There are 1 electron in the hydrogen atom, 7 electrons in the nitrogen atom, and 16 electrons in the oxygen atom. Each atom in HNO3 has 1 valence electron.
How many electron are in a hydrogen atom?
There is only ONE electron in the hydrogen atom . Here is a table of hydrogen isotopes. You will notice in all three cases there is only one proton and one electron. protium ([1/1]p) ; 1 proton, 0 neutrons , 1 electron deuterium ([2/1]d) ; 1 proton, 1 neutron , 1 electron tritium ([3/1]t) ; 1 proton, 2 neutrons , 1 electron NB helium ([4/2]He) ; 2 protons, 2 neutrons, 2 electrons.
How many protons and neutrons does a hydrogen Atom contain?
One hydrogen atom contains one proton and one electron.
