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.
The nucleus of a radioactive element does not break down and give off particles and energy?
false
Is true or false that the crystals in each mineral are the same shape?
Crystals of a certain mineral have a regular formation of atoms. However, crystals of the same mineral can grow differently. The presence of trace minerals, variations in heat, pressure, and the space that they have to grow in can influence the shape of a crystal. Crystalline structures demonstrate characteristic geographic variations for these reasons.
True or false all matter is made of atoms?
Technically false, because of the words "spin around". That's not how elecgtrons really work. They exist as spherical standing probability functions. If that's what you meant by "spin around", then yes, it's true.
Is it True or false the greater the distance the stronger the electric field?
It is false.
Electric currents will pass along a pencil lead true or false?
False, Pb (lead) is an electrolyte and can pass electricity VERY efficiently, but unfortunately pencil "lead" is actually graphite, which is a derivative of stone, and will not effectively pass an electric current.
Correction or changes to the official daily schedule are usually made in pencil is it true or false?
False
True or false a chemical is always the same thing as an element?
FALSE
Is The first element on the periodic table of element helium.?
False.
The first element in a compound is positive and the second one is negative.?
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.
True or false that hydrogen is the least common element in the universe?
It is false.
In alpha decay the parent element and the daughter element can be different isotopes of the same element but in beta decay the parent and daughter element are always the same?
No. In both the cases the element would definitely change. As alpha particle comes out then the new element would have two less in atomic number where as in beta particle decay the new element will have one higher in atomic number.
An MICR device senses the presence or absence of a mark such as a pencil mark?
False
Electrons are the smallest particle of an element that retains the original characteristics of the element?
No. This is a definition of an atom. Electrons are only part of atoms.
True or false a compound can only have one element?
false because a compound has to have two elements to become a compound so if it's just one element it's just a element.
The collection of natural numbers is an example of an element true or false?
false -apex life
