unstable
It varies from one element to another. It is measured in terms of its half-life. A half-life is the length of time it takes for half the number of radioactive atoms of the element in a lump to decay.
Francium has an atomic covalent radius of 260 pm, is radioactive and very unstable.
True and False. Radioactivity is a characteristic of unstable atomic nuclei, whereas radioactive decay is the process that a radioactive nucleus undergoes when it decays due to its instability.Argument for true: Radioactivity is the tendency to undergo radioactive decay.Argument for false: The two terms are unrelated because one is a characteristic and the other is a process, and, therefore, the question misunderstands the definition of the terms.You choose your definition. This writer prefers false.
In any element, all atoms are identical in terms of their number of protons in the nucleus, which determines the element's identity. However, atoms of the same element can differ in the number of neutrons, resulting in isotopes.

Atom. An atom is the smallest unit of an element that retains all the properties of that element. It consists of a nucleus containing protons and neutrons, surrounded by electrons.

Your question is a bit vague, as "science terms" is a broad category. However, let's start with the simplest answer: Mt is the symbol for Meitnerium, a synthetic radioactive element.
It is not clear what "greater" means. In terms of atomic number (number of protons in the nucleus) there is not even an element which is twice as great.
In any element, all atoms are identical in terms of their number of protons in the nucleus, which determines the element's identity. However, atoms of the same element can differ in the number of neutrons, resulting in isotopes.
In linguistics, a nucleus refers to the main vowel sound in a syllable. It is typically the most prominent and sonorous element of the syllable and is often a vowel or a syllabic consonant. The nucleus is essential for forming a syllable and can vary in terms of length and quality.
There are many parts to every element on Earth, whether living or not. In terms of an atom the neutron is located in the center or nucleus of the atom.
An answer is impossible without a definition of a "powerful element"; and this syntagma is not adequate for a chemical element. But it is true that plutonium is very dangerous (radioactive and toxic) and expensive.
Each atom of one specific element has the same number of protons. For example, Helium has 1 proton in every atom's nucleus. To find how many protons are in an elements atoms nucleus, look at the elements atomic number on the Periodic Table.
The terms exothermic and endothermic are applicable to chemical or physical reactions, not to materials. But because curium is an radioactive element, of course some thermal radiation is emitted.
