What is Thomson theory?
An atom consists of a sphere of positive charge with negatively charged electron embedded in it,The positive and the negative charges in an atom are equal in magnitude, due to which an atom is electrically neutral. It has no over all negative or positive charge.
What is the meaning of the term electronegativity?
Electronegativity is tendency of an atom to attract shared pair of electrons towards itself in a chemical bond. Since it is only relative electron tendency, it has no specific units. Electronegativity is elated to: (a) Size of an atom. (b) Effective nuclear charge Atom with small size and high nuclear charge has high electronegativity due to the strong pull exerted on shared electrons by the nucleus. For example, fluorine is highly electronegative element with electro negativity value 3.92 due to small size and high effective nuclear charge. Atom with greater size and less nuclear charge has low electronegativity as its nucleus does not exert a stong attractive force on shared electrons. For example, Caesium is least electronegative element with electronegativity value 0.7 due to its big sizes and less effetive nuclear charge.
If an atom has 17 protons 13 neutrons and 19 electrons what is the atoms electrical charge?
An atom with 17 protons and 19 electrons has a charge of -2, due to the excess of electrons.An atom with 17 protons, 13 neutrons, and 19 electrons is an ion of the isotope Chlorine-30, which has a half life of less than 30 nanoseconds, so that atom will not exist very long.
An ion is an atom with a net electrical charge due to .?
Gained or lost electron(s).
What charge is a nucleus?
neutral
What does the charge due to the electrons of a neutral atom do?
balances the charge on the nucleus
An atom which has 4 protons and 6 neutrons will be electrically neutral if it contains?
An atom with 4 protons and 6 neutrons will have a total charge of +4 due to the protons. To be electrically neutral, it needs 4 electrons to balance the positive charge from the protons.
When the number of protons and electrons are the same the atom is neutral?
Yes, that is correct. An atom is neutral when the number of protons in the nucleus (positive charge) is equal to the number of electrons orbiting around the nucleus (negative charge), balancing out the overall charge to zero.
What is the charge for a chromic ion?
A chromic ion, Cr3+, has a charge of +3 due to the loss of three electrons from a neutral chromium atom.
What is the least electromagnetic atom?
Helium is the atom with the least electromagnetic charge due to its stable configuration of two protons and two electrons, resulting in a neutral charge overall.
Is a oxygen and hydrogen atom a positive or negative charge?
An oxygen atom has a partial negative charge due to its higher electronegativity and tendency to attract electrons. A hydrogen atom has a partial positive charge in a molecule due to its lower electronegativity and tendency to lose electrons.
What forms from a neutral atom or molecule by adding electrons to it?
Anion. An anion is formed when a neutral atom or molecule gains one or more electrons, resulting in a negative charge due to an excess of electrons compared to protons.
A strontium atom differs from a stontiun ion in that the atom has a greater what?
A strontium atom differs from a strontium ion in that the atom has a greater number of electrons compared to the ion. This means the atom retains its neutral charge due to an equal number of protons and electrons, while the ion has lost some electrons and carries a positive charge.
What charge does the nucleus of an atom hold?
The nucleus of an atom carries a positive charge. This positive charge is due to the presence of protons in the nucleus. Electrons, which are negatively charged, orbit around the nucleus to balance out the overall charge of the atom.
What is the difference between a neutral atom an ion and an excited atom?
A neutral atom is an atom with an equal number of electrons and protons without any additional energy. An excited atom has electrons that have absorbed energy and moved up to another layer. Ions are atoms that have a different number of electrons from the neutral atom.
Why does an atom have a net zero change?
All atoms of any element are electrically neutral as they will have the same number of positively charged protons and negatively charged electrons in order to maintain electrical neutrality.
Why are atoms considered to have no electric charge?
It is because an atom consists of electrons(negatively charged) and protons(positively charged) and neutrons(no charge), and the no. of electrons and protons are equal. So due to opposite charges between an electron and a proton, an atom has no electric charge or is said to be neutral.
