Review

  • where the mass of an atom is concentrated

    the nucleus

  • charge of an atomic nucleus

    positive

  • what holds an atom together

    electrostatic attraction

  • deflection of electrons in an electric field

    very easily away from negative plate, towards the positive plate

  • why is an electron easily deflected

    have a very small mass

  • deflection of protons in an electric field

    away from positive. towards negative

  • why are protons deflected less than electrons

    protons are heavier than electrons

  • deflection of neutrons in an electric field

    none at all

  • proof of subatomic particles charge

    deflection in an electric field

  • ions are

    charged

  • formation of an ion

    either gain or loss of electrons

  • atomic (proton) number is the same as

    the number of protons

  • calculation of number of protons

    mass number - number of neutrons

  • a neutral atom has the same numbers of

    protons and electrons

  • a positive ion has

    lost electrons

    fewer electrons than protons

  • a negative ion has

    gained electrons

    more electrons than protons

  • formula for number of neutrons

    mass number - number of protons
