What particles exist in plasma that do not exist in all elements in other states?
Plasma is a fundamental state of matter containing ionized (negative or positive) atoms, molecules and electrons.
What does electronegative and electropositive mean?
Electronegativity is a property that describes the tendency of an atom to attract electrons.An atom with a higher electronegativity number will attract more electrons towards it.Electropositivity is the opposite - so an atoms ability to donate electrons and form positive (or partially positive) ions.
Which of these describes the charges of an atom's electrons and protons?
Protons have a POSITIVE charge Neutrons don't have a charge, hence the name NEUTRON Electrons have a NEGATIVE charge Protons and Neutrons form the nucleus of the atom and Electrons spin around the nucleus
What is the Bohr's model?
a Bohr model is a diagram of an atom that describes the arrangement of the subatomic particles(electrons, neutrons, and protons) protons and neutrons are in the nucleus and the electrons in the electron shells.
Examples of ionic and covalent compounds?
Ionic compounds: NaCl, KOH, CuSO4, etc. Any compound containing a metal and a non-metal. In ionic compounds, metals have positive ions (they lose electrons to the non metal) and non-metals have negative ions (as they gain electrons from the metal) Covalent compounds: CH4, BF3, NH3, all hydrocarbons/ all compounds containing only non-metals.
What term describes a reaction where a positive ion gains electrons?
anode
Is it possible for an atom to be not neutral?
Yes, an atom that is not neutral (that is, it is either positive or negative) is referred to as an ion. Ions containing MORE protons than electrons are considered "positive". Ions containing LESS protons than electrons are considered "negative".
What describes Rutherfords model of an atom?
Rutherford imagined the atom to be a particle with a thickly concentrated positive nucleus and electrons moving around it.
A spherical mirror produces positive linear magnification What is the nature of the image?
The nature of the image that a spherical mirror produces positive magnification is usually enlarged when compared to the real object.
What best describes Rutherford's model of an atom?
Rutherford imagined the atom to be a particle with a thickly concentrated positive nucleus and electrons moving around it.
Does electrons have positive charge?
No, electrons are negative. Protons are positive, and neutrons are neutral.
What can be a negative for electrons or a positive for protons?
The charge of electrons is negative and of protons is positive.
What particles exist in plasma that do not exist in all elements in other states?
Plasma is a fundamental state of matter containing ionized (negative or positive) atoms, molecules and electrons.
Shape of micrococcus luteus?
A gram positive microorganism that is the cause of meningitis meningitis A gram positive microorganism that is the cause of meningitis
What charges do proton an electrons have?
Pprotons have a positive charge neutrons have no charge and electrons have a negative charge. However the one with the smallest mass is electrons.
How current flow from positive to negative terminal in cell?
DC current. Some experts argue that indications show that electrons flow from negative to positive (According to current arguments), but it is assumed generally that electrons flow from positive to negative.
What does electronegative and electropositive mean?
Electronegativity is a property that describes the tendency of an atom to attract electrons.An atom with a higher electronegativity number will attract more electrons towards it.Electropositivity is the opposite - so an atoms ability to donate electrons and form positive (or partially positive) ions.
