Why atomic number is expressed by protons and not electrons?
electrons change the charge of an atom, not the element itself.
What is the net charge of CH2?
Carbon has a charge of -4 by itself. Each hydrogen atom contributes +1, so the net charge then, is -2.
What is the negetive charge in the nucleus?
The negative charge in the nucleus comes from the electrons. Electrons are negatively charged particles that orbit the nucleus of an atom. The nucleus itself contains positively charged protons and neutral neutrons.
What is The formal charge on the carbon atom in the carbonate ion?
the formal charge of carbon in carbonate ion is 0solutionvalence electron-4non bonded electron-0and total no of bonding electrons=8formal charge = valence - non bonded - 1/2 total number of bonding electronselectron electron= 4-0-4= 0
Which line of electrical charge is found on the oxygen atom of a polar water molecule?
The oxygen atom in a polar water molecule carries a partial negative charge. This is because oxygen is more electronegative than hydrogen, pulling the shared electrons closer to itself and creating a partial negative charge on the oxygen atom.
What changes the charge of the atom?
what changes the charge of the atom
Why is that water is describe as apolar solvent?
Due to the ability of the nucleus of oxygen atom to attract the electrons of the covalent bond to itself is higher than that of the nucleus of hydrogen atom, so oxygen atom carry partial negative charge and hydrogen carry partial positive charge
What will be the charge of a neutral atom?
A neutral atom will have a charge of ZERO
How do bonded atoms become partially charged?
Due to the difference in the electronegativities of the bonded atoms, the more electronegative atom attracts the shared pair of electrons towards itself, which increases the negative charge density around the attracting atom, consequently the other atom has less negative charge density and thus a positive charge density (relatively positive) gets generated at the donor atom.
Is oxygen is a positive charge?
No. On its own oxygen is neutral. Its ion, the oxide ion, has a negative charge
What is a polar atom?
A polar atom is an atom that has a positive and negative charge distribution within its structure, typically due to differences in electronegativity. This causes the atom to have a slightly positive charge on one side and a slightly negative charge on the other side. Water (H2O) is a commonly cited example of a polar molecule, with oxygen being the polar atom as it pulls the shared electrons more strongly towards itself.
If the number of protons exceeds the number of neutrons is the charge on the atom positive or negative?
If the number of protons exceeds the number of neutrons, the atom itself is neutral in charge because protons are positively charged and neutrons are neutral. However, if you're referring to charged particles, an excess of protons (compared to electrons) would result in a positive charge for the atom, making it a cation. In summary, an atom's charge is determined by the balance between protons and electrons, not neutrons.
