What else can I help you with?
The nucleus of a radioactive element does not break down and give off particles and energy?
false
True or false water is an example of a chemical element?
False. Water is a molecule made of 2 parts hydrogen one part oxygen. NOT AN ELEMENT.
Which is a true statement about the atomic nucleus. It takes up most of the volume of the atom. It contains protons neutrons and electrons. It contains most of the mass of the atom?
The first two statement are false. The other one is true. There are electrons outside the nucleus, but they are much lighter than the particles in the nucleus.
What does the pH scale measure the concentration of?
The pH scale is a Science indicator, Not a Mathmatical one :-)
True or False The central core of an atom is called a HUB?
I'm not really sure if it's called a HUB, but I do know that the central core of an atom is called the nucleus, and is made out of protons (with a positive charge) and neutrons (with no charge).
If an particle hits a gold nucleus in a head on collision the particle will not be deflected very much?
Correct, due to the massive size of the gold nucleus compared to the size of the incoming particle, the particle will not experience a large deflection in a head-on collision. This is because of the concentrated positive charge in a small space in the gold nucleus that causes a very strong Coulomb repulsion when the incoming particle gets close to it.
When two hydrogen nuclei combine to form one helium nucleus fusion has taken place true or false?
Yes it is true. In fusion reactions, two nuclei (not necessarily be hydrogen) combine to form a larger nucleus.
When two hydrogen nuclei combine to form one helium nucleus nuclear fusion has taken place true or false?
Yes it is true. In fusion reactions, two nuclei (not necessarily be hydrogen) combine to form a larger nucleus.
True or false a nucleus is an atomic particle that has no atomic charge?
Assuming the context of this question is atomic physics, the answer is "false" for two reasons: 1) the atomic nucleus is positively charged. 2) the atomic nucleus a tightly bound composite of many particles.
Which of the follwing is false about a neutral atom of hydrogen?
To accurately identify a false statement about a neutral atom of hydrogen, we need specific options to evaluate. However, in general, a neutral atom of hydrogen has one proton in its nucleus and one electron orbiting it, resulting in no overall charge. If a statement claims that a neutral hydrogen atom has more than one electron or a different number of protons, it would be false.
Equivalent weight is that weight of a substance which combines wit or displaces 1.008 parts of weight of hydrogen or 8 parts by weight of oxygen true or false?
false
The smaller the soil particle the coarser it will be?
false
State true or false Hydrogen is insoluble in water?
False False False FalseFalse
Is meiosis involves one division of the nucleus and cytoplasm?
False and why
Basic particle from which all elements are made?
At its most basic all matter is made up of various quarks. Quarks come in six flavours as both quarks and antiquarks. They form electrons, protons and neutrons. These larger particles form the atoms of all elements.
True are false a nucleus is the outer part of a cell?
False, it is in the center of the cell
True or false that hydrogen is the least common element in the universe?
False. Hydrogen is the most abundant element in the universe, constituting about 75% of its elemental mass.
