Molybdenum is the element that has 42 electrons.
Electrically neutral elements have equal numbers of electrons and protons. A stable element has equal numbers of protons and neutrons. Thus, the answer to the question ''Do Eletrically neutral element have equal numbers of electrons and neutrons?'' depends on the stability of the element i.e. if stable then yes and if unstable than might not.
The numbers of protons and electrons are identical.
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
All atoms of an element contain the same number of electrons and protons but they can have different numbers of neutrons. Atoms with different numbers of neutrons are isotopes.
An atom is electrically neutral when the number of protons equals the number of electrons. Since the atom has 42 protons, it will also have 42 electrons, regardless of the number of neutrons. Therefore, this atom will have 42 electrons.
molybdenum
Maybe it can be electrons or mass numbers
42 electrons implies atomic number of 42, which implies that it's molybdenum. With 42 electrons implies 42 protons implies an atomic mass of 42+53=95 which is 95Mo, one of the stable isotopes of this element. Please see the link.
(6)====Molybdenum is within group 16. If in group 1 then it has 1, if group 2 then it has 2. If in the teens, drop the 1. So this element is in group 16 so it has 6 valence electrons. Try Chlorine- notice it is in group 17 so it has 7 v electrons.
Electrically neutral elements have equal numbers of electrons and protons. A stable element has equal numbers of protons and neutrons. Thus, the answer to the question ''Do Eletrically neutral element have equal numbers of electrons and neutrons?'' depends on the stability of the element i.e. if stable then yes and if unstable than might not.
+2 implies that 2 electrons are lost by the element. -2 implies that 2 electrons are gained by the element
+2 implies that 2 electrons are lost by the element. -2 implies that 2 electrons are gained by the element
You can tell if a substance is an element or not by it's atoms. If it's a pure element, it will only have one type of atom (e.g. Copper atoms). If it's not an element it will have two or more types of atoms in it (e.g. Copper, Carbon and Lithium atoms). You can tell which element an atom is by the amount of electrons it has (atomic number) For Example: Hydrogen: 1 electron: Atomic Number 1 Helium: 2 electrons: Atomic Number 2 Molybdenum: 42 electrons: Atomic Number 42 Seaborgium: 106 electrons: Atomic Number 106
put it in your mind! The Atomic number. is number of protons, While The Mass number. is number of protons and electrons. when you subtract both get the number of electrons and this for any element but not all elements have same atomic numbers or mass and Rutherford First discover "transmutation" from element to other element which determine by their atomic and mass numbers.
NO. Isotopes are forms of an element that have the same numbers of protons and electrons, but differing numbers of neutrons. For example Helium-3 has two protons, two electrons, and one neutron and Helium-4 has two protons, two electrons, and two neutrons.A form of an element that has a different number of electrons than the number of protons is an "ion".
The number of protons and electrons in a neutral atom are the same and given by the element's atomic number.
Arsenic is a non metal element. There are 33 electrons in a single atom.
