What else can I help you with?
Oxidation involves the gain of electrons for a substance. true or false?
False. Oxidation involves the loss of electrons for a substance.
When elections are transferred between two atoms a covalent bond is formed true or false?
This is false. Transfer of electrons produces an ionic bond.
Covalent bonds are formed when two or more atoms share protons. true or false?
False. Definitely false. Only valence electrons are shared in covalent bonds, hence the name:co for shared and valent for valence electrons. Neutrons are never shared, as they are about 1,800 times the mass of an electron, and are also a part of the nucleus. Giving up a neutron would result in another isotope of the element.
Is it true that Unlike protons or neutrons electrons have no mass?
no electrons have mass, about 1/1800 that of a proton or neutron.
The weight of subtomic particles is measured in units called atomic mass units true or false?
Yes, true: the mass of 1 proton is exactly the same as of 1 neutron: 1 a.m.u.
True Or False most of an atom's volume is the space in which electrons move?
True, most of an atom's volume is the space in which electrons move.
True or false The troposphere contains almost all of the mass of the atmosphere?
True. The troposphere is the lowest layer of Earth's atmosphere and contains approximately 75-80% of the total mass of the atmosphere.
Oxidation involves the gain of electrons for a substance. true or false?
False. Oxidation involves the loss of electrons for a substance.
True or false Most of an atom is empty space?
True. The protons and neutrons together are dense and comprise most of the mass of the atom. The electrons "circle" around in a "cloud" so there is empty space in between the electrons.
Is it true that A proton is 24 times more massive than a neutron?
False. The mass of proton and neutron are almost similar.
True or false Covalent bonds can best be describe as a swapping of electrons?
False. Covalent bonds involve the sharing of electrons between atoms, not the swapping of electrons.
Is it true or false every element has the same valence?
False. Elements have different numbers of valence electrons, which determines their reactivity and chemical properties. The valence electrons are the electrons in the outermost energy level of an atom.
Is this true or false that almost all cells have nucleas?
It is true.
When elections are transferred between two atoms a covalent bond is formed true or false?
This is false. Transfer of electrons produces an ionic bond.
True or false Slavery almost destroyed the black family?
False
Covalent bonds are formed when two or more atoms share protons. true or false?
False. Definitely false. Only valence electrons are shared in covalent bonds, hence the name:co for shared and valent for valence electrons. Neutrons are never shared, as they are about 1,800 times the mass of an electron, and are also a part of the nucleus. Giving up a neutron would result in another isotope of the element.
A GRADUATE is used to musure mass true or false?
true
