Elohim is used as one of the many names of God to describe how he is interacting with the universe, Earth, or man. Christians like to use it to mean that it is the Trinity which is a not Jewish/Hebrew concept, but only a pagan one.
Elohim has plural morphological form in Hebrew, but it is used with singular verbs and adjectives in the Hebrew text when the particular meaning of the God of Israel (a singular deity) is traditionally understood. Thus the very first words of the Torah (in the book you call Genesis) are “bresheet bara elohim”, where “bara” is a verb inflected as third person singular masculine perfect.
If “Elohim” were an ordinary plural word, then the plural verb form “bar’u” would have been used in this sentence instead. Such plural grammatical forms are in fact found in cases where “Elohim” has semantically plural reference. There are a few other words in Hebrew that have a plural ending, but refer to a single entity and take singular verbs and adjectives, for example “be’alim” which means “owner” in Exodus 21:29.
So you don’t know.
