How many electron potons and mass number...

How many electron potons and mass number in a nucleus of atomic number `11` and mass `24`?
(i) number of electron = (ii)number of proton = (iii)number of neutrons =

Text Solution

Verified by Experts

Number of protons in nucleus =atomic number` 11`
Number of elcectrons in an atom =Number of protns `=11`
Number of neutrons = mass number (A) - atomic number `(Z) =24 -11 =13.

    The nucleus of an atom has 5 protons and 6 neutrons. What would be the (a) atomic number, (b) mass number, (c) the number of electrons, and (d) the number of valence electrons, per atom of this element ?

    Which of the following are true for an element ? (i) Atomic number = number of protons + number of electrons (ii) Mass number = number of protons + number of neutrons (iii) Atomic number = number of protons = number of neutrons (iv) Atomic number = number of protons = number of electrons

    Atomic number of a nucleus is Z and atomic mass is M . The number of neutron is.

    The number of electrons in an element with atomic number X and mass number Y will be

    Arrange the following statements in a sequence which involves the calculation of the atomic number and mass number for an atom of an element with 15 electrons and 16 neutrons. (1) A = Number of protons + Number of neutrons A = Z + Number of neutrons A = 15 + 16 = 31 (2) Number of protons and number of electrons are equal in a neutral atom. Hence, the atomic number Z is equal to 15. (3) Mass number is equal to the total number of protons and neutrons. (4) Atomic number is 15 and mass number is 31.
