A piece of pure Iron contains only one type of atom (Iron atoms) but there is more than one atom in it.
The expression true or false atoms is not correct. All atoms are true entities. Each isotope of an element has a different number of neutrons; the number of protons and electrons is constant for all the isotopes of an element.
Dalton's atomic theory proposed that all atoms of a particular element are identical, which we now know is not entirely true. Isotopes are atoms of the same element with different numbers of neutrons, leading to variations in atomic mass. This discovery challenged Dalton's rule of identical atoms for a given element.
No,. The halogens will gain 1 electron when they react if electrons are exchanged.
False. A molecule is the smallest part of a compound that can still be indentified as a compound as it may contain several atoms of different elements. A single atom can only identify a single element, not a compound which it may have been a part of.
False. Places in the same hemisphere can have different seasons due to factors such as distance from the equator, elevation, and proximity to large bodies of water. These factors can influence the climate and result in variations in the timing and intensity of seasons within the same hemisphere.
True apex
No atom has the same number of protons as another atom, unless both atoms are atoms of the same chemical element.
True. The number of atoms in a mole of an element is determined by Avogadro's number, which is a constant (6.022 x 10^23) regardless of the element being considered. Each element's molar mass in grams is equal to one mole of that element's atoms.
No . all the atoms have same no of protones.....
false
All atoms of the same element are the same.7) Isotopes are a family of atoms all of which have the same number of electrons, have the same number of protons in their atomic centers, but different numbers of neutrons.
FALSE
Yes, it is true.
True - the element is carbon
No. This is a definition of an atom. Electrons are only part of atoms.
The expression true or false atoms is not correct. All atoms are true entities. Each isotope of an element has a different number of neutrons; the number of protons and electrons is constant for all the isotopes of an element.
Today this affirmation is not generally valid.
